Introduction

1.1

About the DESIGN Reference Manual The PDMS DESIGN Reference Manual describes all the DESIGN commands in detail. It also describes how the Design database is structured, the Design database elements and their attributes. DESIGN is normally used interactively. The Graphical User Interface (GUI) provides discipline-based applications which help you to create, check and report on the model. How to use the applications is described in user guides and on-line help. This manual is written for experienced users of PDMS DESIGN who need to use commands; for example, to write batch macros or to customise the GUI. If you are going to customise the GUI, you will also need to refer to the Cadcentre Software Customisation Guide and Cadcentre Software Customisation Reference Manual for information about PML, the Cadcentre programming language.

1.2

Organisation of the DESIGN Reference Manual The DESIGN Reference Manual has four parts: •

Part 1 (this volume) describes general DESIGN commands, which are used, for example, for setting up the display, and querying and navigating around the Design database. It also describes how to use the command syntax graphs, which are used to show all the options available for each command.

•

Part 2, Creating the Model, describes the commands for creating database elements and setting their attributes.

•

Part 3, Elements and Attributes, contains details of all the elements which can be created in the Design database, their position in the database hierarchy and their attributes.

•

Part 4, Utilities, describes the DESIGN Utilities for data consistency checking and clash detection, and for exporting DESIGN data to programs such as REVIEW.

Introduction

1.3

Organisation of this Manual This manual, Part 1, is divided into the following chapters:

1-2

•

Chapter 2 describes How to use the Syntax Graphs, and also shows the standard syntax graphs which are often referenced from other graphs.

•

Chapter 3, General PDMS Commands, describes commands used for saving work, setting units and tolerances, and handling alphanumeric output. These commands are common to several PDMS modules, but are included here for convenience.

•

Chapter 4, Design Databases and MDBs, describes how to handle multiple databases from within DESIGN, database sessions, how to query information about the project, and how to used multiwrite databases.

•

Chapter 5, Display, describes how to control the way the model is displayed in a graphical view.

•

Chapter 6, Using Rules, gives some examples of using rules in DESIGN to control attribute settings.

•

Chapter 7, Interacting with a Graphical View, describes how commands can accept input from picked items in the graphical view, and how to define construction aids and label the design elements. Note that the commands in this chapter have generally been superseded by newer graphical facilities available from the GUI, and are only included as information for users maintaining older code.

•

Chapter 8, Design Database Elements, describes the commands to create Design elements and set the attributes common to all Design elements, and how to navigate about a Design database hierarchy.

•

Chapter 9, Error Messages, explains some of the error messages which may be generated by DESIGN.

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

How to Use the Syntax Graphs The commands described in this chapter are presented in the form of syntax graphs. •

Syntax graphs are read from top left to bottom right. The start point is shown by >, and you can follow any path through the graph until the exit point, shown by >, is reached.

•

Points marked with a plus sign (+) are option junctions which allow you to input any one of the commands to the right of the junction. For example: >----+--- ABC -----. | | |--- PQR -----| | | `-------------+--->

means you can type in ABC or PQR or just press Enter to get the default option. •

Text in angle brackets <. . . > is the name of another syntax graph. This convention is used for syntax which occurs in many places. The graphs referred to are described at the end of this section. For example: >----+--- ABC -----. | | |--- PQR -----| | | |--- ---| | | `-------------+--->

means you can type in ABC or PQR or any command allowed by the syntax given in diagram or just press Enter to get the default option. •

Points marked with an asterisk (*) are loop back junctions. Command options following these may be repeated as required. For example: .-----<-------. / | >---*--- option1 ---| | | |--- option2 ---| | | `--- option3 ---+--->

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

2-1

How to Use the Syntax Graphs

means that you can enter any combination of option1 and/or option2 and/or option3, where the options can be commands, other syntax diagrams, or command arguments. The simplified format: .----<------. / | >---*--- name ----+--->

means that you may type in a list of PDMS names, separated by at least one space.

2.1

Commands Commands are shown in a combination of uppercase and lowercase letters, where the capital letters indicate the minimum abbreviation. (Note: This convention does not mean that the second part of the command must be typed in lowercase letters; commands may be entered in any combination of uppercase and lowercase letters.) For example, the command CONStruct can be input in any of the following forms: CONS CONST CONSTR CONSTRU CONSTRUC CONSTRUCT Commands shown in all uppercase letters cannot be abbreviated.

2.2

Command Arguments Command arguments are shown in lowercase letters. These are just descriptions of what you need to enter. The most commonly used descriptions are as follows:

2-2

integer

A positive or negative whole number. For example: 2 –5 25

value

A signed number with or without a decimal point. For example: 2.5 5 –3.8

letter

A single alphabetic character

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

How to Use the Syntax Graphs

word

A sequence of up to four letters, e.g. GATE WN P (may be longer in some cases, but only the first four characters are significant).

text

A string of alphanumeric or symbol characters, which may include spaces, enclosed between single closing quotation marks or | characters. This is normally used to add descriptive material to an appropriate attribute. For example DUTY ’Low Pressure’

space

The space bar (not usually specified unless of special significance)

name

A sequence of characters preceded by a slash / and representing a PDMS Element name. For example: /BRANCH7 /305.ABC /P4/NOZ Note: A name should always be followed by a space (unless at the end of a line).

filename An external file name of the form /filename varid

An identifier (for use with the VARIABLE command within macros) of the form !name where ‘name’ is a text string. For example: !COUNTER,

comma

!height

The ‘,’ character, which can be used to concatenate DESIGN commands. For example: NEW FLANGE SELECT WITH STYP WN, CONNECT

plus minus star slash These are the + (add), – (subtract), * (multiply) and / (divide) operators, which can be used in arithmetic expressions. For example: (1 + 2), (1 – 2), (1 * 2), (1 / 2) Note that there must be a space before and after each of these operators. Note:

PML 1 expressions and variables are explained in the Cadcentre Software Customisation Reference Manual.

How to Use the Syntax Graphs

2.3

Standard Syntax Graphs If a syntax graph refers to a second syntax graph, the name of the second graph is shown in angle brackets. This convention is usually used for standard syntax graphs which are widely used. These syntax graphs are summarised below, and then shown in detail.

2.3.2 Date/Time has the general format Time Day Month Year. Time has the format hour:mins. If no Time is given, the default is 23:59. Day is a single or two-digit integer. If no Day is given, the default is today. If no Time is given, Day must be specified. Month may be entered as a word, or as a number surrounded by spaced / characters. If no Month is given, the default is the current month. Year may be entered as four digits or as two digits. Two-digit years are interpreted within the date window current_year – 99 to current_year For example, in the year 2004:

03 04 05

means means means

2003 2004 1905

If no year is given, the default is the current year. Examples 12:00 22 August 1999 9:30 29 / 8 / 99

How to Use the Syntax Graphs

2.3.11 Selection <selatt> This syntax lets you describe elements you want to include in, or exclude from, operations. Typically, the following criteria are used to define a selection: •

A class of elements or element types to be selected. You can specify whether all members are to be included, or whether only items (the lowest level components in the hierarchy below a given element) should be included. See <selcla> below.

•

A logical expression to be satisfied for all selected elements. These expressions return either True or False, and are usually used to check the values of attributes. See the Cadcentre Software Customisation Reference Manual.

•

A physical volume in which all selected elements must lie. This volume is always orthogonal to the World coordinate axes. You can specify this in terms of two diagonally opposite points of an enclosing box, or as a volume around an element (with an optional clearance around the element selected). See <selvol> below.

•

A point in the hierarchy below which all selected elements must lie. You can follow this with an exclusion list to exclude elements from the selection. See <selhie> below.

•

A list (or collection), such as a drawlist, obstruction list or claimlist, of which the selected elements must be members.

All of these criteria are optional, except for class. If all element types are valid, this should be ALL. If you specify more than one criterion, the specifications must be in the above order, as shown by the following graphs: <selatt>= >-+- ALL -----------------------. | | | .------<-----. | | | | | ‘- <selcla> -*- <selcla> -’ | | | ‘----------------+--. | .-----------------<------------------------’ | +- WIth --. | | |- WHere -+- <expr> -. | | ‘--------------------+- <selvol> -. | | ‘------------+- <selhie> -. | | ‘------------+- <selfrom> -. | | ‘-------------+-->

How to Use the Syntax Graphs

ALL PIPE WITHIN VOLUME /PIPE1 1500

Selects all piping elements within a volume defined as a box drawn around /PIPE1, with a clearance of 1500mm between the edges of /PIPE1 and the volume box. You can minimise the time taken for any selection operation by making the selection criteria as specific as possible, so that only relevant parts of the databases are searched for the required elements. Where known, specify the element type (e.g. ALL BOX ...), the database element under which the search is to be restricted (e.g. ALL BOX FOR /ZONE1 ...), the volume in which you are interested (e.g. ALL BOX WITHIN N5000 E5000 U0 TO N10000 E12000 U8000 ...), and so on. If you do not do this, all databases in the current MDB will be searched, whether or not they contain relevant types of element, and performance will be impaired.

2.4

Command Input Modes Generally, in DESIGN you are able to access the full range of DESIGN command syntax. However there are two modes where the syntax is restricted to commands only relevant to that mode. The modes are: •

MDB mode allows you to change or query databases during a DESIGN session. Described in Chapter 4.

•

DESCLASH mode allows you to check the design for clashes. Described in the Design Reference Manual Part 4: Utilities.

To return to normal DESIGN mode, enter the command EXIT.

General PDMS Commands

3.1

Entering DESIGN

Keyword:

DESIGN

Description:

Enters DESIGN. This command is available throughout PDMS.

3.2

Saving

3.2.1 Saving DESIGN Work Keyword:

SAVEWORK [n] GETWORK [n]

Description:

SAVEWORK saves the current DESIGN changes without leaving DESIGN. It is good practice to use this command on a regular basis during a long DESIGN session to ensure maximum data security. The optional number n can be used to specify a particular database for the command. The number is the number of the database in the order output by the STATUS command (see Section 4.2). If no number is given, the SAVEWORK applies to the whole MDB. GETWORK refreshes the view of all READ databases to pick up any changes that other users may have made since you first opened them. The optional n works in the same way as for SAVEWORK. You would normally only use GETWORK if you know of specific changes you wish to pick up and use. Please note that GETWORK slows up subsequent database access, as the information has to be re-read from disk. Therefore, you should use this command sparingly.

3.2.2 Saving and Restoring the Display Keywords: RECREATE INSTALL Description:

These commands let you save and restore the graphical view(s) and the forms as displayed before you exit from DESIGN.

NOTE: Forms resized or moved using the cursor will be INSTALLed to their original size. PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

3.3

The Alpha Display

3.3.1 Saving the Alpha Log Keywords:

ALPHA LOG

Description:

Lets you save the alpha display information to a text file. Two types of output are available, depending on the command used.

ALPHA FILE

ALPHA LOG enables the contents of either or both of the COMMANDS and REQUESTS alpha regions to be written to a file. ALPHA FILE enables the contents of the REQUESTS regions only to be written to file. The ALPHA LOG and ALPHA FILE commands may be used to save data such as the results of a data consistency check, or be used as a general output facility. NOTE: After an ALPHA file has been opened, subsequent output will be directed to both the file and the screen until the file is closed, or until you change to another PDMS module.

QUIT FINISH

Description:

QUIT exits from DESIGN without saving any changes or the display setup. QUIT has the effect of deleting any changes made since the last SAVEWORK, module change or MDB change. FINISH also exits from DESIGN without saving any changes, but in this case you are taken directly to the operating system of your computer.

Examples: QUIT

Exit from DESIGN (and enter MONITOR)

3.5

Setting Working Units and Tolerances These functions let you set the dimensioning units and precision for design placement and element searching operations. The designer can choose at any time to work with metric or imperial units and can differentiate between the units used for nominal pipe bores and for general linear dimensions. Tolerance settings are available for general 3D positioning, plus special tolerance controls for pipe and structural steelwork layouts. A search radius (the ‘hit radius’) can be specified for cursor picking operations.

3.5.1 Setting Working Units Keywords:

MILLIMETRE

Description:

You can choose to work with units for nominal bores and dimensions other than those specified in the Catalogue. The PDMS default is to work in millimetres for nominal bores and distances. However, the Catalogue can contain company-specific instructions that alter the defaults; say, feet and inches. After the units setting is changed, all input and output will take place in the new units unless specifically stated.

MM

INCH

FINCH

Examples: MM BORE All bores will be input and output in mm FINCH DIS All distances and coordinates will be input and output in feet and inches UNITS /PERCHES All distances and coordinates will be input and output in the units defined in the units definition element /PERCHES in the Properties Database UNITS DEF Uses the default Catalogue database units UNITS

‘Standard’ PDMS units

NOTE: 3 feet 6 inches must be input as 3’6 when using FINCH units.

3.5.2 Setting Output Precision of Distance Units NOTE: You must not change the precision if you are customising the Cadcentre Applicationware. You should only use this command if you are writing a completely new application. Keywords:

PRECISION

Description: Output dimensions, in the current units, are normally rounded to the following degrees of precision: Millimetres

To the nearest mm (e.g. 316)

Inches

To the nearest 0.1 inch (e.g. 38.8)

Feet and inches

To the nearest 1/32 inch (e.g. 3’7.15/32)

Output for setting variables defaults to the following, higher, precisions: Millimetres

To two decimal places (e.g. 316.25)

Inches

To two decimal places (e.g. 38.75)

Feet and inches

To the nearest 1/64 inch (e.g. 3’7.31/64)

You may control the output precision of distances in some modules by using the PRECISION command. This allows you to specify the number of decimal places for MM or INCH output, or the largest fraction denominator for FINCH output. Precision levels for general output and for the setting of variables are specified separately.

3-6

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

General PDMS Commands

To specify the output precision, use the command: PRECision opt1 DIstance opt2 value opt3 where the command options (opt1, opt2 and opt3) are as follows: opt1 defines how the specified precision is to be applied. It is one of the following: OUTput VARiables

For general dimensions For setting variables

If opt1 is omitted: •

Both Output and Variables are set if opt2 is DEFAULT

•

Output only is set if opt2 is TO

opt2 defines whether you are changing to a newly-defined precision or back to the default settings. It is one of the following:

TO DEFault If opt2 is omitted, TO is assumed. opt3, which only applies if opt2 is TO, qualifies the number specified by value. The available choices are:

DECimals DPls THs NDs

Decimal places

Decimal places As in 64ths As in 32nds

If opt3 is omitted, value is assumed to apply as follows: •

If current units are MM or INCH:

value is Decimals

•

If current units are FINCH:

value is THs or NDs

Examples: PREC OUT DI DEF

Set default precision for output

PREC VAR DEF

Set default precision for variables

PREC DI DEF

Set default precision for output and variables

PREC DI 1 DP

Set output to 1 decimal place (MM or INCH units)

PREC OUT DI 4 DEC Set output to 4 decimal places (MM or INCH units) PREC VAR DI 3 DP Set variables to 3 decimal places (MM or INCH units) PREC DI 64THS

3.5.3 Switching between Actual and Nominal Bores The PRECISION command also allows you to output actual bore dimensions (rather than Nominal bore values) when required. To switch to output of actual bore dimensions, use the command: PRECISION BORE ACTUAL To switch back to using nominal bore values: PRECISION BORE NOMINAL

3.6

Audible Error Trace

Keywords:

ALARM

Description:

When a macro error occurs, there is an audible alarm at the workstation to signal that the error has occurred. Occasionally, macro errors can be anticipated and no audible warning is required. This command allows the audible warning to be switched on or off either interactively or via a macro. If the audible warning is ON, it will sound whenever an error alert is displayed. The default settingis ON .

Examples: ALARM ON

Sets the audible tone to be on.

ALARM OFF

Suppresses the audible tone until it is turned on again.

Examples:

Note:

TRACE OFF

Stops the automatic output of Current Element name.

TRACE ON

Restarts automatic output of Current Element name.

ON is the default setting.

Command Syntax: >-- TRAce --+-- ON ---. | | ‘-- OFF --+-->

3.8

Giving Operating System Commands from PDMS

Keywords:

SYSCOMmand

Description:

PDMS normally assumes that any command input in response to its prompt character (*) is an instruction to the current module, and will check its validity on that assumption. You can issue an operating system (OS) command to the host computer from within PDMS by enetring the SYSCOM command. followed immediately (without pressing Return) by the OS command enclosed between apostrophes (’) or vertical bars (|). The effect applies only to the single command line; as soon as the OS command has been executed, control is returned to PDMS.

NOTE: Do not try to issue OS commands which might disrupt PDMS operations; for example, commands which would close or amend files currently in use by PDMS. Examples: SYSCOM 'dir'

3.9

General Querying Facilities You will often find, when working in PDMS, that you need to check existing information about some aspect of the program’s operations; for example: •

Current usage in terms of users, modules and DBs.

•

The currently selected output device.

•

The unique code which identifies the process you are running and the station you are running it from (useful for generating unique workfile names).

•

The current setting, perhaps the default setting, of a command option.

•

The contents of part of a particular DB; for example, the current setting of an attribute or the list of member elements owned by a specific element.

•

The elements which match specific selection criteria entered by you.

To ask for such information from within DESIGN, type Query

(almost always abbreviated to Q)

followed by the relevant querying option as described in the following sections. (You also will find more specific querying syntax throughout this set of manuals.)

3.9.1 Querying Your Current Module To check the version number or revision date of your current module, enter one of the following: Q BANner Q BANner FULL This will cause PDMS to redisplay the banner which was shown when you first entered DESIGN. For example: Design Mk11.3.1 (WINDOWS-NT 4.0) (29 Feb 2000 : 22.40) (the FULL option will also display data about the software components used by DESIGN).

3.9.2 Querying Your System To ask about your current MDB, enter Q MDB To output all valid teams for the current user, enter Q TEAM 3-10

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

Sessions Each time you enter DESIGN or save your design changes, a new session is created for each database changed. You can then query when specific items of design data were modified by reference to the corresponding session number(s). Sessions can be used by the System Administrator to backtrack changes to a given date or session if necessary.

4.5.1 Session Comments You can add a comment for each session, which can help identify the work done in each session. Keyword:

SESSION COMMENT

Description:

Lets you associate comment text with the current design session. You can query this text later to help you identify a particular session in which modifications were made to elements and/or attribute settings. You should enter the session comment before you issue a SAVEWORK command.

Note:

Sessions 1 and 2 are created in ADMIN (when the DESIGN DB and its World element, respectively, are created), so the first true DESIGN session will be Session 3.

HISTORY

Description:

Lets you query modification history for a given attribute; i.e. session numbers during which the attribute was modified.

Examples: Q HISTORY DIAM Gives all sessions in which DIAM attribute was modified. Note:

HISTORY is an array type pseudo-attribute, so that qualifying positions may be appended to query specific occurrences in the modification history. For example: Q HISTORY[2] DIAM gives second most recent session in which DIAM attribute was modified. History records are restricted to a maximum of 120 sessions.

Command Syntax: Q HISTORY attribute_name

Examples: Q SESSION ON 12:00 22 August 1995 Q SESSION ON 9 / 9 /96 Time defaults to 23:59, so returns last session number on given date. Command Syntax: Q SESSION ON where is a standard syntax graph, see Chapter 2. Remember that actually specifies a time (to the nearest minute), so take care if you use any defaults here.

4.8

Using Multiwrite Databases If a DESIGN DB has been created as a multiwrite database, several users can write to it simultaneously, although they cannot change the same element. Multiwrite databases can either be Standard multiwrite databases, or Extract databases. In both types, an element must be claimed before it can be modified. Claiming an element prevents other users claiming (and modifying) the element; the element must be unclaimed or released before another user can change it. Claiming can be either explicit, where the user must use the CLAIM command before attempting to modify the element, or implicit, where the claim is made automatically when the user tries to modify the element. The claim mode is set when the DB is created. For full details see the PDMS ADMIN Reference Manual.

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

4-9

DESIGN Databases and MDBs

4.8.1 User Claims Keywords:

CLAIM

Description:

In a Standard multiwrite database, you must claim an element before changing it. This is known as a user claim. If the claim mode is explicit (see below for details of how to check this), you must first claim each element that you want to modify using the CLAIM command. If the claim mode is implicit, the claim will be made automatically (although you can still give explicit CLAIM commands if you want to prevent other users claiming specific elements).

UNCLAIM

Only significant elements can be claimed, that is: WORLD SITE ZONE EQUI SUBE PIPE BRAN STRU SUBS FRMW SBFR REST HANG SCTN GPWL PANE HVAC PTRA RPLG You can claim a specified element only, or a specified element plus all of the significant elements below it in the hierarchy. If the claimed element is not a significant element, the significant element above it in the hierarchy will be claimed. An element must be unclaimed before another user can claim it and change it. User claims are always unclaimed when you change modules or leaves PDMS, and you can also unclaim elements at any time during a PDMS session using the UNCLAIM command. Examples: CLAIM /ZoneA /EQUIP100 /PIPE-100-A Claims named elements CLAIM /ZoneA HIERARCHY Claims named element and all of its owned hierarchy CLAIM /ELBOW-33 Claims Branch which owns named component, since ELBO is not a significant element UNCLAIM /PIPE-100 /PIPE-200 Unclaims named elements UNCLAIM ALL Unclaims all elements currently claimed Command Syntax: .---------------. / | >-- CLAIM ----*-- elementname --+-- HIERARCHY ---. | | ‘----------------+-->

4.8.2 Notes on Standard Multiwrite DBs •

Elements cannot be claimed if recent changes have been made to them by other users. You must issue a GETWORK command first.

•

Elements cannot be unclaimed if there are updates outstanding. You must issue a SAVEWORK command first.

•

You can insert/remove significant elements in a members list without claiming the owner. For example, you can add a Branch to a Pipe without claiming the Pipe. Thus two users can add different Branches to the same Pipe: any discrepancies will be resolved when a SAVEWORK is attempted.

•

Before an element can be deleted, that element and all of its subhierarchy must be claimed.

•

The following potential problems may not be revealed until you try to save changes: •

If two concurrent users allocate the same name to different elements, the second user to attempt a SAVEWORK will show up an error. The second user must rename their element.

•

If one user inserts a significant element into another element’s list, while a concurrent user deletes the latter element, an attempt to SAVEWORK will show up an error. Either the first user must delete or move the significant element, or the second user must QUIT without saving the deletion.

4.8.3 Extract Databases Keywords:

EXTRACT REFRESH ISSUE FLUSH RELEASE DROP

Description:

Unlike standard multiwrite databases, extracts allow users to keep elements claimed when they exit from PDMS or change module. They can also be used, together with Data Access Control, to manage workflow. See the PDMS ADMIN User Guide for more information. An extract is created from an existing Database. When an Extract is created, it will be empty, with pointers back to the owing or master database. Extracts can only be created from Multiwrite databases, and all extracts are themselves Multiwrite. An extract can be worked on by one User at the same time as another user is working on the master or

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

4-11

DESIGN Databases and MDBs

another extract. When a user works on the extract, an extract claim is made as well as a user claim. If the claim mode is explicit, the extract claim will be made automatically when you make a user claim using the CLAIM command. You can also claim to the extract only using the EXTRACT CLAIM command. If an element is claimed to an extract, only users with write access to the extract will be able to make a user claim and start work on the element: •

If the databases are set up with implicit claim, when the user modifies the element, the element will be claimed both to the extract and then to the user. If the element is already claimed to the extract, then the claim will only be made to the user.

•

If the databases are set up with explicit claim, then the user will need to use the CLAIM command before modifying the element.

•

Once a user has made a user claim, no other users will be able to work on the elements claimed, as in a normal multiwrite database.

•

If a user unclaims an element, it will remain claimed to the extract until the extract claim is released or issued. When an extract User does a SAVEWORK, the changed data will be saved to the Extract. The unchanged data will still be read via pointers back to the master DB. The changes made to the extract can written back to the master, or dropped. Also, the extract can be refreshed with changes made to the master.

Examples: EXTRACT CLAIM /STRU1 /STRU2 /STRU3 Claims named elements to the extract EXTRACT CLAIM /STRU1 /STRU2 /ZONE-A HIERARCHY Claims the named elements, and all the elements in the hierarchy to the extract The HIERARCHY keyword must be the last on the command line. It will attempt to claim to the extract all members of the elements listed in the command which are not already claimed to the extract. EXTRACT FLUSH DB PIPE/PIPE Writes all changes to the database back to the owing extract. The Extract claim is maintained. EXTRACT FLUSH /STRU1 /STRU2 /STRU3 Writes the changes to the named elements back to the owing extract. The Extract claim is maintained. 4-12

EXTRACT DROP DB PIPE/PIPE Drops changes that have not been flushed or issued. The user claim must have been unclaimed before this command can be given. The elements required can be specified by selection criteria, using a PML expression. For example: EXTRACT CLAIM ALL STRU WHERE (:OWNER EQ ‘USERA’) HIERARCHY

4.8.4 How to Find Out What You Can Claim Keywords:

Q CLAIMLIST

Description:

Before you start work on an extract, you should do a GETWORK and an EXTRACT REFRESH, which will ensure that you have an up-todate view of the database. This section explains what different users will see as a result of Q CLAIMLIST commands. For this example, take the case of a database PIPE/PIPE, accessed by USERA, with two extracts. Users USERX1 and USERX2 are working on the extracts.

DB PIPE/PIPE USERA

DB PIPE/PIPEX1

DB PIPE/PIPE-X2

USERX1

USERX2

USERA creates a Pipe and flushes the database back to the owning database, PIPE/PIPE. The results of various Q CLAIMLIST commands by the three Users, together with the extract control commands which they have to give to make the new data available, are shown in the Figure 3-1. Note: Q CLAIMLIST EXTRACT tells you what you can flush Q CLAIMLIST OTHERS tells you want you can't claim

Figure 3-1

Querying extract claimlists

When you create an element, PDMS only sees it as a user claim, not an extract claim, until the element is flushed. It will then be reported as an extract claim (as well as a user claim, if it has not been unclaimed). Note that a change in the claim status of an existing element will be shown by the appropriate Q CLAIMLIST command as soon as appropriate updates take place, but a user will have to GETWORK as usual to see the changes to the Design model data. We recommend that:

DESIGN Databases and MDBs

•

Before you make a user or extract claim, you should do an EXTRACT REFRESH and GETWORK.

•

If you need to claim many elements to an extract, it improves performance if the elements are claimed in a single command, for example, by using a collection: EXTRACT CLAIM ALL FROM !COLL

Examples: Q DBNAME Returns the name of the database which you are actually writing to. Q CLAIMLIST Outputs a list of all elements currently claimed by yourself: Q CLAIMLIST OTHER Outputs a list of all elements currently claimed by other users who are accessing the same DB: Q CLAIMLIST EXTRACT Shows the extract claimlist for all the writable extracts in the MDB. Q CLAIMLIST EXTRACT DB dbname Shows the extract claimlist for the named extract DB. Q CLAIMLIST EXTRACT FREE DB dbname Shows the elements claimed to the current extract and not claimed to another extract or user. That is, the elements which can be released Q CLAIMLIST EXTRACT OTHER DB dbname Shows the elements claimed to the current extract and claimed to another extract or user. Q CLAIMLIST CONTROL DB dbname Shows the extract claimlist for a CONTROLLED named extract DB. Q DBAC Queries the access mode of the database. DBAC is a pseudo-attribute which can have the text settings CONTROL, UPDATE or MULTIWRITE. Q DBCL Queries the claim mode of the database. DBCL is a pseudo-attribute which can have the text settings EXPLICIT or IMPLICIT. Q LCLM Queries whether or not the current element is claimed by another user. Returns TRUE or FALSE.

Comparing Database Changes

4.9.1 Comparing Database States at Different Times You can compare details of your current database settings with the corresponding settings at a specified earlier time and generate a report listing all differences. The types of change reported include: •

Creation and deletion of elements.

•

Changes to the attribute settings of elements.

•

Changes in the list order for BRANCH, POGON, DRAWI and BOUND elements.

Keywords:

DIFFERENCE

Description:

Lets you report all changes to one or more specified database elements since an earlier version of that database. The output is in the form of a report listing all elements and attributes which have changed, with their old and new values. The report can be sent to a file by using the ALPHA FILE or ALPHA LOG commands.

Note:

SINCE

The database states are compared between SAVEWORK operations. For example, if you last saved your design changes at 9:30 and ask for a comparison since 10:00, the current settings will be compared with those at 9:30.

Examples: DIFFERENCE ALL BRANCH FOR /ATEST SINCE 21 JANUARY DIFF CE SINCE 10:00 Assumes current day. DIFF /ZONE1

4.10 Creating Database Update Macros The OUTPUT command produces macros which can be re-input to recreate or modify specified parts of the DESIGN DB. You can include only the elements which have been changed since a specified time (i.e. those elements which would be listed by the DIFFERENCE command). The output is generated in three stages: 1.

Any elements which were originally locked are unlocked. Element deletions, name changes and type changes are output. Note that reordering or insertion of elements in their owner’s members list is treated as deletion followed by creation, so that Refno attribute settings may be changed.

2.

Newly created elements and all standard attribute settings are output.

3.

Reference attribute settings and rules are output. Elements which were originally locked are relocked and GADD commands are included if any elements were included in Groups.

Keywords:

OUTPUT

Description:

Lets you output all changes to one or more specified database elements since an earlier version of that database. The output is in the form of a macro which can recreate the changes when run on, say, a copy of the original DB. The macro is sent to a file by using the standard ALPHA FILE or ALPHA LOG commands.

The macro is sent to a file by using the standard ALPHA FILE or ALPHA LOG commands (see Section 3.3). You can also give a PDMS session number. The database states are compared between SAVEWORK operations. For example, if you last saved your design changes at 9:30 and ask for a macro containing changes since 10:00, the macro will contain all changes since 9:30.

4.11 Inter-DB Connection Macros Access to a DB is usually controlled in such a way that only one user can modify the content of that DB at any one time; that is, only one user can have Write access to the DB. Other users may have simultaneous Read access, depending how access rights have been set up in the ADMIN module. (See also Section 4.9, which describes a new multiwrite DB facility.) In a multi-disciplinary PDMS project, in which different teams of users work on different aspects of the design, an individual user will usually have PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

4-19

DESIGN Databases and MDBs

Read/Write access to the DBs controlled by their own team and Read-only access to DBs controlled by other teams. This works well until a user needs to connect an item in their team’s DB to an item in another team’s DB; for example, a member of the Piping team may wish to connect a Branch in a Piping DB to a Nozzle in an Equipment DB (to which they have Read-only access). In such a case, the design changes needed in the Equipment DB are stored in a ‘buffer’ file known as an inter-DB connection macro. Only when this macro is run by a member of the Equipment team, with Write access to the Equipment DB, are the changes implemented. The sequence of events which would occur is illustrated in the following example. Assume that Project ABC has separate Piping and Equipment design teams. Assume that User P has Read/Write access to a Piping DB and Read-only access to an Equipment DB, while User E has Read/Write access to the Equipment DB and Read-only access to the Piping DB. User P wishes to connect a Branch Tail in their Piping DB to a Nozzle in User E’s Equipment DB; that is, they wish to set the Branch’s TREF in their Piping DB to point to the CREF of the Nozzle (which they can do) and to set the CREF of the Nozzle to point to the TREF of their Branch (which they can not do), thus: Only User E can set this Branch in Piping DB owned by User P's team

CREF

TREF

Nozzle in Equipment DB owned by User E's team

Only User P can set this

•

User P sets the TREF of their Branch to point to the CREF of the Nozzle in the Equipment DB.

•

When User P tries to set the Nozzle’s CREF, they receive a message telling them that they are trying to connect to a read-only DB and that an inter-DB connection macro is being created automatically. This macro, which stores the commands needed to set the CREF, is given a name with the format abc001.mac (where the macro number, 001 here, is allocated sequentially), and is held in the directory ABCMAC (or as defined by the project’s environmental variables).

•

When User E next enters MONITOR (usually when entering or leaving PDMS), they receive a message asking them to run the inter-DB connection macro abc001.mac and to delete it when they have done so.

•

User E enters DESIGN and runs the inter-DB connection macro by giving the command $M /%ABCMAC%/abc001.mac

4-20

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

DESIGN Databases and MDBs

This sets the CREF for the Nozzle to point to the TREF of the Branch and completes the link between the two DBs. •

User E enters MONITOR (or ADMIN if they have sufficient access rights) and deletes the redundant macro by giving the command DELETE MACRO 1 where 1 is the macro number.

Note:

If User P checks their DB for data consistency errors between Stages 2 and 4, when the macro has been created but not yet run, they will get an ‘incompatible connection reference’ message. They cannot finalise their design until User E has run the macro. Thus, the successful use of inter-DB connection macros relies on good co-operation between the teams involved. Inter-DB connection macros are also created in multiwrite DBs if an attachment is claimed by another user.

Adding Elements to the Display

Keywords:

ADD COLOUR

Description:

Allows selected Design items to be added to the Draw List, which defines which elements are to be displayed. If an element is to be displayed in a colour which is different from the default colour, this can be specified as part of the command line. Items added to the display are added to all volume views with the scale and view direction appropriate to that view. The Draw List can contain significant elements only. Significant elements in DESIGN are: EQUI

SUBE

DATU

GRDM

PTRA

BOUN

BRAN

HANG

PVOL*

RPLA*

STRU

SUBS

SCTN

PNOD

PALJ

PANE

(* only if directly below a Site or Zone.) If an element below a significant element (i.e. a primitive) is added, then the whole significant element will be added as well. If an element above a significant element (e.g. a PIPE) is added, then all significant elements owned by that element will be added; not the high-level element itself. Examples: ADD /P100A

/P100A is added to the Draw List

ADD CE

The current element will be added to the Draw List

ADD /ZONE1 /ZONE2 COLOUR 5 /ZONE1 and /ZONE2 will be added in colour 5. If you wish to add items in other colours, you must use separate commands. PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

5.1.1 Selecting Graphics Colours Automatically Keywords:

AUTOCOLOUR

Description:

Lets you define a set of rules for automating the selection of colours for items added to graphical views. Each rule consists of a set of selection criteria for particular types of element, together with an associated colour (which may be an explicit colour number or an expression). When an element is added to the drawlist, the selection rules are scanned in sequence until a rule is found to be true for that element. The element is then added in the colour corresponding to that rule. If the colour is invalid, the search is continued. If no rule is true for the element, the default colour is used. The order in which the rules are set up is significant, since the first rule found to be true determines the colour. Automatic colour selection may be switched on or off as required. If it is on, the colour specified by the rule is used rather than any other

colour entered as part of the ADD command. If dynamic autocolouring is specified, the autocolour will be checked every time an attribute is changed and, if necessary, the relevant element will be readded in the current colour. Each autocolour may be drawn either as a solid colour (default) or as a translucent shade. If using translucency, you can also specify whether or not the edges of an item should be drawn (as in wireline mode) to give a more distinct outline. Examples: AUTOCOLOUR ALL EQUI COLOUR 4 All Equipment items to be added in colour 4 AUTOCOLOUR ALL EQUI COLOUR 4 TRANSLUCENCY 25 EDGES ON All Equipment items to be added in colour 4 with 25% translucency and edges drawn. AUTOCOLOUR ALL BRAN WITH (HBORE GT 100) COLOUR 10 All Branches with head bores greater than 100 to be added in colour 10. AUTOCOLOUR ALL SCTN COLOUR (:COLOUR OF SPRE) All Sections to be added as defined by the UDA :COLOUR derived via their SpecRefs. AUTOCOLOUR ALL COLOUR (:COLOUR) Uses the UDA :COLOUR to denote the colour for all displayed elements. If you enter this as the final rule, it will provide a default colour if all other rules prove false. AUTOCOLOUR ON

Colours will be chosen according to autocolour rules. If Off (the default), colour specified in the ADD command will be used.

AUTOCOLOUR DYNAMIC ON Updates autocolour each time an attribute changes. (Use with care!) AUTOCOLOUR RESET Clears all current autocolour rules. AUTOCOLOUR REMOVE 2 Removes the second rule from the current list. AUTOCOLOUR REORDER 2 TO 4 Moves rule number 2 to position 4 in the list.

5.1.2 Removing Elements from the Display Keywords:

REMOVE

Description:

These commands remove elements from the Draw List and the display.

Examples: REMOVE /BRANCH1

/BRANCH1 will be removed from the Draw List and the display

REM SITE /PIPING The site /PIPING will be removed REM ALL Note:

All items in the Draw List, and on the screen, will be removed

If an element below a significant element (i.e. a primitive) is removed, then the whole significant element will be removed as well. This is because the Draw List may only contain significant elements. Significant elements are EQUI, SUBE, DATU, GRDM, PTRA, BOUN, BRAN, HANG, PVOL*, RPLA*, STRU, SUBS, SCTN, PNOD, PALJ, PANE. (* only if directly below a Site or Zone.)

5.1.3 Defining Colours Keywords:

COLOUR ACTIVE CE VISIBLE CLASH OBST AIDS

Description:

These commands allow colours to be defined so that different types of item in the display may be distinguished by means of colour. Certain items such as current element and active element colours have default settings, but these may also be redefined. The colours may be assigned by using the COLOUR command to define the Red-Green-Blue mix for a colour number or to assign a predefined colour mix by name. DESIGN allows the use of 115 user-definable colours, plus some specific ones which are assigned to items which need to be readily distinguishable in the display.

Definitions: •

The Active element is the significant element (and its components) being worked on.

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

Display

•

The Current Element (CE) is the actual element currently being accessed.

•

The Visible design consists of the design elements which you wish to be displayed (but which you are not currently working on).

•

A Clashing element is an element whose current position and geometry are being tested for interferences against other elements in the design and which has been found to clash (see Chapter 15).

•

An Obstructing element is any of the elements in the design against which a clashing element is being tested for interferences and which has been found to clash (see Chapter 15).

•

An Aid includes tags (markers), axes and other graphical annotations.

The predefined colour mixes which you may specify by name are as follows: Colour black white whitesmoke ivory grey lightgrey darkgrey darkslate red brightred coralred tomato plum deeppink pink salmon orange brightorange orangered maroon yellow gold lightyellow lightgold yellowgreen

5.2.3 Setting Drawing Level Representation Keywords:

REPRESENTATION LEVEL

Description:

This command enables individual drawing levels to be specified for the display of piping, nozzles, structural elements and other design database elements. Every basic primitive shape in the design has an associated drawing level range attribute (for piping and structural steelwork components, these are stored in the Catalogue). If the specified drawing level coincides with this range, the 3D object will be drawn when it is added to the Draw List. The practical effect of this facility is that it allows you to minimise visible detail when representing Design items. For example, at drawing level 3 steelwork may be represented as single line only, whereas at level 1 the full detail may be visible. Level 3 may well be adequate for design purposes.

5.2.4 Setting Obstruction and Insulation Representation Keywords:

REPRESENTATION OBSTRUCTION INSULATION TRANSLUCENCY

Description:

Component Obstructions are often given LEVELS or TUBE and CENTRELINE settings which render them invisible. Setting the Representation of OBST On forces the system to override normal LEVEL and TUBE settings and show all of the primitives, regardless of the other settings. Setting the Representation of INSU On or Off determines whether or not insulation is shown on primitives.

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

5-11

Display

These have the effect of considering all primitives which have an obstruction level greater than zero and all primitives which are affected by insulation parameters. As with changes to LEVEL representation, the graphics display is not updated instantly. Items must be removed and re-added to the Draw List to become visible. To avoid obscuring the view in colour-shaded mode, obstruction and/or insulation can be shown as translucent, the degree of translucency being controllable. Examples: REPR OBST ON INSU OFF REPR INSU ON REPR INSU ON TRANSLUCENCY 25 Command Syntax: .------------------------------<---------------. / | >- REPResentation -*- OBSTruction -. | | | | ‘- INSUlation --+- ON --+------------------------| | | | | '- TRANSLucency - value -| | | ‘- OFF --------------------------+->

When p-points are on, they are drawn as small arrows with a cross at the p-point position and with the arrow indicating the p-point direction. The size of the arrow is controlled by the LENGTH option. Ppoint numbers may also be displayed, as controlled by the NUMBERS option. As with changes to other representation settings, the graphics display is not updated instantly. Items must be removed and re-added to the Draw List before changes to the display of p-points becomes visible. Examples: REPR PPOINTS ON Sets the p-point representation to ON REPR PPOINTS LENGTH 5 Sets size of p-point arrows REPR PPOINTS NUMB ON Shows p-point numbers Command Syntax: .----------<----------. / | >-- REPResentation --*-- PPoints --+-- ON ---| | | |-- OFF --+--> | |-- LENgth -- value --> | ‘-- NUMbers --+-- ON ---. | | ‘-- OFF --+-->

5.2.6 Setting Structural Node Representation Keywords:

REPRESENTATION PNODES SNODES

Description:

These options allow Primary and/or Secondary Nodes on structural steelwork items to be shown on the display in specified colours and sizes. By default, both types of node are shown in the current visible colour, with a size equivalent to 10mm diameter.

Examples: REPR PNOD ON Only Primary Nodes will be shown in the display. PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

5.2.9 Setting Arc Tolerance Representation Keywords:

REPRESENTATION DARCTOLERANCE

Description:

Controls the arc tolerance used when representing certain curves as polygon segments or facetting planes. The smaller the arc tolerance, the smoother the curve drawn, but the slower the graphical performance. The tolerances used for most curve drawing in DESIGN are controlled automatically by the graphical system. The REPRE DARC command controls the following aspects only: •

Filleted vertices used in the representation of extrusions; for example, Section Profiles from the Catalogue, Panel Loops, etc.

•

Items which include holes (but only when REPRE HOLES is set to On; see Section 5.2.8).

The default setting is 10 mm. The minimum permitted setting is 1mm.

Specifying Axes

Keywords:

AXES

Description:

Lets you specify and position a set of axes on the display. The axes represent the compass directions of the World co-ordinate system and may be positioned anywhere on the display. Axes remain visible until they are switched off or deleted. Switching axes off renders them invisible, whilst deletion removes them altogether. Switched-off axes can be made visible again by switching them back on.

Graphical Labelling of Design Elements

Keywords:

MARK

Description:

This facility allows specific design elements or lengths of Tube to be labelled in the display.

UNMARK

Frequently referenced items may be marked with a constant graphic label which will stay with that item even if it is moved or rescaled. Items can also be unmarked (which removes the label). Labels are shown in all permitted regions where the item’s origin is within the current sub-view. The label always points to the origin or, in the case of a Branch or Hanger, to its Head or Tail (where the name will be suffixed with + or – respectively).

5-18

5.5

Using Design Aids

Keywords:

AID LINE ARROW CEARROW ARC SPHERE BOX CYLINDER

Description:

This facility lets you incorporate lines, arrows, arcs, spheres, boxes or cylinders in a view to help you with the design construction. Design aids can be grouped together (using the NUMBER option) and given a number for identification. Aid lines are drawn between two defined 3D positions. The linestyle can be solid, dashed, dotted or dash-dot, and you can label them with text markers at defined positions. Aid arrows are used to complement lines for showing dimensions etc. You can control both the overall height of an arrow and the proportion of its height occupied by the conical arrow-head, thus changing its emphasis.

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

5-19

Display

A special aid arrow, the CEArrow, is positioned automatically to point to the current element. You can specify whether the arrow points to the Origin (default), P-arrive or P-leave of the current element. NOTE: These terms relate primarily to piping components. For other element types, they are interpreted in a logical way. For example, for a SCTN, Origin = P-arrive = POSS, P-leave = POSE; for a PANE, Origin = Vertex 1; for a VERT, Origin = vertex position; etc. Aid arcs are defined in terms of two points at their extremities and either a third 'through' point or a tangent point through which a second-order Bezier curve is constructed. Aid spheres are defined by the position of the centre and the radius. Aid boxes are defined in terms of their position, orientation, and X,Y,Z dimensions. They may be drawn in wireline mode (like penalty volumes or clipping boxes) or in solid mode (like box primitives). Aid cylinders are defined in terms of their position, orientation, diameter and height. They may be drawn in wireline or solid (filled) mode. Examples: AID LINE E1200S3500U0 TO E760N1200U50 Draws a line between the two 3D positions. AID LINE NUMBER 5 E1200S3500U0 TO E760N1200U50 LINESTYLE DOTTED Groups the new line with other such lines with the same number (5 this example) and draws it in the dotted linestyle. AID CLEAR LINE 5 Deletes line number 5 AID ARROW AT E760N1200U50 DIR E HEI 100 PROP 0.5 Positions 100mm arrow with given position and direction; arrow head is 50mm long. AID BOX POS PIN 6 ORI X IS UP Y TOWARDS /PUMP1 XLEN 200 YLEN 200 ZLEN 200 FILL OFF Positions a wireline cubic box, with 200mm sides, at Pin 6 with the specified orientation.

Spatial Maps Spatial maps of the model are based on the obstruction limit boxes surrounding each Design element, rather than using fully detailed geometric representations. The spatial maps allow faster data access, and they are used for tasks such as clash detection where fast data access is required and where the simplified representation is adequate. Spatial maps are maintained automatically as the design model is updated, but may need to be rebuilt explicitly if the Catalogue data, from which the map geometry is derived, is changed.

5.7.1 Checking the Spatial Maps Keywords:

MAP CHECK

Description:

You can check one or more of the spatial maps to ensure that they accurately reflect the current state of the design. To avoid spurious results, it is advisable to do this before carrying out a clash check. This is particularly important if the geometry of any geometry elements has been modified.

Examples: MAP CHECK MDB Checks the spatial maps for all Design DBs within the current MDB against the current design and catalogue data. If there are any discrepancies, appropriate messages are output; you should then rebuild the map (see Section 5.7.2) MAP CHECK PIPES/AREA1 Checks the up-to-date status of the spatial map for the named Design DB only. Command Syntax: >--- MAP CHEck ---+--- MDB -------------------------------. | | | .-----------<---------. | | / | | ‘--- word ---*--- name --+-- word ---’ | | | ‘--------------+--->

Using Rules to Define Attribute Settings Rather than being set explicitly, the values of some types of attribute can be specified in terms of rules; that is, expressions from which the attribute values can be evaluated. Rules can be set only for attributes of the following types (including user-defined attributes): text, scalar (integer, real or logical), position, orientation, direction; they cannot be set for reference attributes. A static rule will change the attribute setting only when verified or executed explicitly, whereas a dynamic rule will update the attribute setting whenever any part of the expression changes (the default type is static).

6.1

Setting Attribute Rules

Keywords:

RULE

Description:

Lets you set a rule for the value of a single named attribute. The rule may contain any valid expression of the type applicable to the attribute setting.

SET

Examples: RULE SET ZLEN (XLEN + YLEN) Sets rule that ZLEN of the current element is the sum of its XLEN and YLEN values. The ZLEN will be updated to reflect changes to XLEN or YLEN only when the rule is verified or executed (i.e. it is a static rule). RULE SET XLEN DYNAM (YLEN + 2) XLEN will be updated automatically whenever YLEN is changed. RULE SET POS (N300 E400 U500) ON ALL BOX FOR /PUMP1 Sets rule for position attribute for all boxes in /PUMP1 RULE SET POS DYNAM (N100 FROM /BOX2 ) If /BOX2 moves, the element with this attribute rule will move with it automatically. (Note space between last character of element name and closing parenthesis.)

Interacting with a Graphical View Note:

7.1

The commands described in this chapter should not be used very often. Most of the functionality they provided has been superseded by Eventdriven Graphics, and they are included here for compatibility with earlier versions of PDMS.

Identifying Displayed Items and Points A displayed element from the visible model can be accessed directly by moving the cursor over it and clicking the left-hand mouse button. The following sections describe the different ways of selecting database elements from the display by using the cursor. These commands let you use the visible design in order to move to elements in the Design hierarchy and points in 3D space. In each case, an appropriate prompt is displayed.

7.1.1 Identifying Displayed Elements using the Cursor Keywords:

IDENTIFY

Description:

If a particular type of element is to be located, a selective search can be made using the IDENTIFY command followed by a keyword identifying the element type. If a specific element type is not requested, the element hit will always be a geometric primitive or component. Any displayed line or p-point of an item may be hit. To abort, press the Cancel button on the displayed form.

Examples: ID @

Pressed Enter (or Return), move the cursor over the desired item and click the left-hand mouse button. The name of the element under the cursor is displayed on the command line. The picked element becomes the current element and is displayed in a different colour. (This is the general response to all variations of the IDENTIFY command.)

ID EQUIP @

As above, but the search is restricted to EQUI elements.

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

7-1

Interacting with a Graphical View

Command Syntax: >-- IDentify --+-- <snoun> --. | | ‘-------------+-- @ -->

7.1.2 Identifying Tube using the Cursor Keywords:

IDENTIFY TUBE

Description:

Variable length Tube (and Rod) from the visible design can be accessed by picking with the cursor. As Tube is not an element in the Design hierarchy, it cannot be accessed. Instead, the component on the upstream side of the Tube (downstream if routing backwards) will be accessed. This means that the next component to be created will be inserted in the picked Tube. Any visible Tube can be picked regardless of whether it is shown in single or double line representation.

Examples: ID T @

The name of the component on the upstream side of the Tube under the cursor is displayed on the command line.

Command Syntax: >-- IDentify Tube @ -->

7.1.3 Identifying Displayed Points using the Cursor Keywords:

IDPPOINT PPOINT

Description:

The cursor can be used to pick any p-point in the visible design or any mapping pin. This form of picking will not change the current element.

Note:

IDPPOINT cannot be used in isolation. It must be used with another command. Only those p-points which are defined in the Catalogue as being visible in DESIGN will be available for picking in this way.

Examples: Q IDP @

7-2

Press and hold down left-hand mouse button when cursor is over element. Element will be highlighted with p-points visible and cursor will change to a square shape. With left-hand mouse button still held down, move cursor over required p-point. When over a p-point, cursor will change to a square shape with crosshairs. Release the button to select the p-point.

7.1.4 Identifying Items with a 2D Pick Use a working plane in preference to this older functionality. Keywords:

TWODPLANE

Description:

This facility lets you define a plane which is normal to the view direction. You can then use the cursor to pick a point in an orthogonal view such that the third coordinate of the required point is derived automatically from this plane.

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

TWODPICK

7-3

Interacting with a Graphical View

The TWODPLANE command defines the 2D picking plane in terms of a point within the plane. The AT TWODPICK @ command may then be used to request a cursor position which identifies a point within the 2D picking plane. The plane is generated dynamically from the TWODPLANE point and the view direction. Examples: TWODPLANE E 1000 N 2000 U 500 Defines 2D picking plane which passes through given point and which is normal to view direction AT TWODPICK @

Note:

Using the preceding 2D picking plane definition, a cursor hit at E 1234 N 5678 in a plan view will return the position E 1234 N 5678 U 500 in World coordinates

Cursor positions are always returned in World coordinates. In order to obtain the correct result, the 2D picking plane must therefore be set to an absolute World position.

Command Syntax: >-- TWODPLane -- --> >-- AT TWODPick @ -->

Querying: >-- Q -- TWODPLane -->

7.2

3D Pins The DESIGN pins are a set of ten temporary marker points which have a 3D position and direction. They can be moved around using positioning and orientation commands similar to those available for permanent Design elements. Once positioned, a pin may either be used as a static reference point or as a temporary p-point. The commands described here only show how to make pins visible and position and orientate them. Once this has been done they can be used for positioning and orientating Design elements in any command that uses point as an argument.

7.2.1 Setting a Pin’s Position and Direction Explicitly Keywords:

PIN AT DIRECTION

Description:

The position and direction of a pin can be set explicitly in the same way as an ordinary design element. Unless stated otherwise, the positional parameters described below are in the coordinate system of the current element.

Examples: PIN 5 AT E1000

Pin 5 will be moved to the coordinate position East 1000 from the Site origin.

PIN5 DIR W WRT SITE Pin 5 will be orientated in a direction West with respect to the current SITE. Command Syntax: >-- PIn integer --+-- AT --+-- ------------------------. | | | | ‘-- POLar DISTance --| | | ‘-- DIRection -----------------------+-->

7.2.2 Making a Pin Visible Keywords:

PIN

Description:

This command allows a particular pin to be switched in and out of the Display. When a pin is visible, it will be drawn as a numbered arrow marker which indicates its position and direction in each volume view. Visible pins can be hit with the cursor during any IDPPOINT operation. When a pin is switched off, it is erased from the display, but it still exists and can be referred to by name.

Examples: PIN 5

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

Pin 5 will be drawn into all volume views, and can be hit by the cursor. 7-5

PIN 5 OFF

Pin 5 will be erased.

Command Syntax: >-- PIn integer --+-- OFF --. | | ‘---------+-->

Querying: (As in previous subsection.)

7.2.3 Locating a Pin by Copying or Connecting Keywords:

PIN

Description:

A pin’s position and direction can be set by copying or connecting to any other p-point or pin, the only difference being that the CONNECT operation orientates the specified pin in the opposite direction (see examples below).

COPY

CONNECT

Examples: PIN 5 C0PY IDP @

Pin 5 will be placed at the same position and orientation as the p-point or pin hit by the cursor.

PIN 5 CONNECT TO PH Pin 5 will be placed at the Branch Head, but pointing in the opposite direction to HDIR (Head direction). This command must be given at BRANCH level. Pin 5 can be an existing pin or a new one. Command Syntax: >-- PIn integer --+-- Copy --------------. | | ‘-- CONnect --+-- TO --| | | ‘--------+-- <marke> -->

7.2.4 Moving a Pin Keywords:

PIN

Description:

These commands allow a pin to be moved from its current position in any axis direction or along its own direction. If moved along its own direction, a specified distance can be given or, alternatively, an intersection. (Moving in this manner is very similar to the piperouting options.)

BY

THROUGH

DISTANCE

Examples: PIN 6 BY E3000 N2000 Pin 6 is moved by the given directions and distances PIN 6 DIST 600

Pin 6 is moved along its own direction by the given amount

PIN 6 THR /NOZZ5

Pin 6 is moved along its own direction until it intersects a plane through /NOZZ5

Querying: >-- Q PIN integer --+-- POSition ---. | | ‘-- DIRection --+-- WRT --. | | |-- IN ---+-- --. | | ‘----------------------+-->

7.2.5 General Pin Moves Keywords:

PIN

Description:

Pins may be moved in exactly the same manner as piping components, using the same command options. The movement direction is always in the pin direction, so it is important to ensure that this is appropriate before a move is attempted. As these commands are quite

extensive, they are not repeated here; see the pipe routing commands in Chapter 8. Examples: PIN 6 DISTANCE 600 INFRONT ID @ Pin 6 is moved along its direction until it is 600 distance units in front of the item picked with the cursor. Command Syntax: >-- PIn integer --> (see Chapter 8 for the construction)

7.3

Constructs Note:

Use the Constructs options on the Utilities menu in preference to these older facilities.

Keywords:

CONSTRUCT POSITION DIRECTION LINE PLANE

Description:

The construction aids available in DESIGN let you display coordinates, directions, distances, angles and plane definitions.

DISTANCE

ANGLE

The constructed quantities are written out into the REQUESTS region of your display. These quantities can be written into variables for later use. The commands used to define constructed quantities make use of p-points, p-lines, pins, directions, positions and orientations. The different methods for constructing these entities are: • CONStruct Angle position1 TO position2 TO position3 direction1 AND direction2 line1 line2 line plane plane1 plane2 plane line • CONStruct DISTance position1 TO position2 position TO line position TO plane line1 TO line2 projection of any of the above ALong a given direction 7-8

Design Database Elements This chapter describes the commands to create, copy and name database elements, and also the commands to navigate around the database hierarchy once you have created some elements. These commands can be used throughout DESIGN. For information about creating the elements which build up the model, and setting their attributes, see Part 2 and Part 3 of the Design Reference Manual. For a comprehensive list of all valid PDMS attributes, see the Cadcentre Software Customisation Reference Manual.

8.1

Elements

8.1.1 Creating Elements Keywords:

NEW

Description:

This command creates a new element in the Design hierarchy. The attributes of that element can then be specified or further elements may be created as members. Elements can only be created at appropriate levels in the hierarchy. For example a Site can own a Zone, but not a Valve. In some cases you must navigate to the correct position in the hierarchy before you can create a new element, but in other cases DESIGN will navigate to the correct level automatically: see Examples below. For Branch and Hanger elements, the location of the new Component in their member list defines the route logic. It is therefore necessary to navigate to the Component adjacent to the insertion point in the member list (upstream if routing forwards, downstream if routing backwards). If the new Component is required at the end of the member list then accessing the Branch or Hanger Head or Tail will insert the Component in the correct position.

Examples: NEW ZONE /Z1 The Zone element is created as a member of the current Site. The Zone is now the current element. Its NAME attribute is /Z1.

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

8-1

Design Database Elements

NEW TEE If the current element is the fourth member in a Branch member list, the Tee element is inserted as the fifth member. The Tee is now the current element. NEW EQUIP /1301 If the current element is a Box owned by another EQUIP which is Member 2 of Zone /Z1, the new Equipment element is inserted as member 3 of the Zone and named /1301. The new Equipment is now the current element. NEW GASKET If this command is given when the current element is the Branch Head, the Gasket is inserted as the first member of the Branch and is now the current element. Command Syntax: >-- NEW --+-- name <snoun> --------. | | ‘-- <snoun> --+-- name --| | | ‘----------+-->

Querying: Q LISt

Indicates all the design element types that can be created as members of the current element.

8.1.2 Creating Elements at a Given Position in the Member List Keywords:

NEW

Description:

You can place elements in any location in a legal member list by specifying the existing element adjacent to where the new element is required. The new element may be inserted either before or after the specified element.

Examples: NEW VALVE BEF (At a Branch Component) The Valve will be inserted before the current element in the current list.

(At Site level) NEW ZONE BEF 2 The Zone will be inserted before member 2 of the Site. NEW BOX (At a CYLI which is a member of a STRU) A new BOX will be inserted as the next member of the STRU (after the CYLI in member list order). NEW BOX (At a SUBS which is a member of a STRU) A new BOX will be inserted as a member of the SUBS (at the top of the member list).

8.1.3 Deleting Elements Keywords:

DELETE

Description:

The basic delete operation can only be performed on the current element. Its effect, however, is to delete this element and all its offspring (i.e. members and their members, etc.) from the model. The MEMBERS option only deletes the offspring, leaving the current element intact. When an element is deleted, its owner becomes the new current element.

Examples: DELETE NOZZ Deletes the current element - a Nozzle. The EQUI owning the Nozzle becomes the current element. DELETE ZONE Deletes the current element - a Zone and all its offspring. The Site owning the Zone becomes the current element. DELETE SITE MEM Deletes all the members of the current element (SITE) and their offspring.

8.1.4 Reorganising the Hierarchy Keywords:

REORDER INCLUDE

Description:

If it is necessary to reorganise the hierarchy, two options are available. REORDER allows the elements in a single member list (e.g. Components of a pipe) to be rearranged. INCLUDE allows elements to be relocated to another part of the hierarchy (e.g. an EQUIPMENT may be moved into a different Zone). In both operations the elements and their offspring are transferred to their new location in the Design hierarchy. In the case of INCLUDE, the element’s owner changes. If the old and new owner are in different positions in World coordinates, then the element will change position. Elements can also be moved to new locations in the hierarchy by placing them before or after a specified element.

Examples: REORDER /B /B, which must be in the member list of the current element, is relocated after the current member list position. INCLUDE /EQUIP The current element must be a Zone, which is the only element which can own an Equipment. /EQUIP is inserted into the Zone’s member list. REORD /B AFTER 3 (Both elements must be in the member list of the current element.) Element /B is located after the third element in the member list. INCL /EQUIP BEF 3 The element /EQUIP is brought from its location in another Zone to before the third element in the member list of the current Zone.

8.1.5 Copying This subsection describes how to copy elements, together with their offspring. When elements are copied, all attributes are duplicated except: •

NAME, which must be unique.

•

LOCK, which will always be unlocked in the new element.

Keywords:

COPY

Description:

The COPY command provides an extremely powerful facility. Not only is it possible to copy all the attributes of a specified element into the current element, it is also possible to duplicate any offspring that element may have. This means that anything from a single primitive shape to a whole equipment item (or even a Site) can be copied.

Examples: COPY PREV For example, if both the current and previous elements are Boxes, the attributes of the previous element will be copied to the current element. COPY /EQUIP10 For example, if the current element is an Equipment, the attributes and offspring of /EQUIP10 are copied to the current element. (The NAME and LOCK attributes of the current element do not change.) Command Syntax: >-- COPY --+--------------------. | | |-- ATTributes - OF -| | | +-- LIKE ------------+ -- --. | | ‘-- ADJacent ------ <selatt>------+--->

•

The ATTRIBUTES option copies all attributes (except for direct design references) from the identified element to the current element. The members hierarchy is not copied. The source and current elements do not have to be the same type. If the types are different, only the attributes valid for the target (current) element are copied.

•

The LIKE option works in a similar fashion to ATTRIBUTES, except that any position, direction, orientation or angle atributes are not copied.

•

The ADJACENT option causes a list of elements, selected by <selatt>, to be copied alongside their original positions in the database. For example, if the list included a SCTN and a PNOD, each of these items would be copied so that the new SCTN shared the same owner as the old SCTN, and the new PNOD shared the same owner as the original PNOD. Note that as this option copies elements, rather than just attributes, the COPY option can be used.

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

Design Database Elements

8.1.6 Copying and Renaming Keywords:

COPY

Description:

This command allows automatic renaming of the current element and any new offspring that possess a standard name part. You can also choose to copy only the members (and their offspring) of an element, leaving the attributes of the current element unchanged.

RENAME

Examples: COPY MEM OF /EQUIP10 (At another EQUIP element.) If the current element is an Equipment, all the offspring of /EQUIP10 are copied into the current element. The attributes of the current element do not change. COPY /P1/PIPE RENAME /P1 /P2 The attributes and offspring of /P1/PIPE are copied into the current element. Where /P1 is found as the name or part of the name, it is renamed as /P2 in the current element and its offspring. COPY MEM 4 TO 10 OF PREV BRAN The attributes and offspring of the fourth element in the current element’s member list are copied into the tenth element in the member list of the previous BRAN element in the current member list. Command Syntax: >- COPY -+- MEMbers -+- n -. | | | | ‘-----+- TO n -. | | | | ‘--------+- OF -+- REName name name -. | | | | ‘--------------------| |- ALL OF -. | | | | ‘----------+- -+- REName name name --------------------| | | ‘---------------------------------------+->

8.2

The Standard Design Element Attributes The range of information attributes carried by each Design element depends upon the element type; for example, a Cylinder has DIAMETER and HEIGHT among its attributes, whereas a PIPE has a PRESSURE attribute. All elements, however, possess the following basic core of four essential attributes (known as the standard attributes): TYPE

This is given by the user as part of the element creation command, e.g. NEW BOX (where the TYPE is BOX).

NAME

This can either be provided by the user or, in the case of minor items, is generated automatically (as a reference number).

OWNER

This attribute indicates the element’s owner and is automatically set when the element is created.

LOCK

This is allows you to prevent an element from being altered or deleted.

In addition, most Design elements possess the two additional attributes: POSITION

The position of the element relative to its owner.

ORIENTATION

The orientation of the element relative to its owner.

Both of these attributes are set automatically during 3D element positioning and routing operations.

8.2.1 The Type of Element and its Owner Keywords:

TYPE

Description:

An element’s TYPE and OWNER attributes are set automatically when it is created. They cannot be changed explicitly.

OWNER

Command Syntax: See Sections 8.1.1 and 8.1.2 on element creation (NEW command).

PDMS DESIGN Reference Manual Part 1: General Commands Version11.3

8-7

Design Database Elements

8.2.2 Naming Design Elements Keywords:

NAME

Description:

All elements except the WORLD can be named. Although Design elements are often given suitable names while being created, later name changes can be made by giving a new name or by removing the old name. The name of any element must be unique; that is, not already used for another currently accessible element.

UNNAME

Examples: NAME /ZONE5D The current element is given the specified name provided it has not been used elsewhere. UNN The current element loses its name (it is still identifiable by its automatically allocated reference number). Command Syntax: >-- NAMe --+-- ALL name name --. | | ‘-- name -----------+--> >-- UNName -->

8.2.3 Renaming Elements and their Offspring Keywords:

RENAME

Description:

The name of the current element and offspring can be modified where a standard name part occurs.

Examples: REN ALL /Z1 /Z2 All occurrences of /Z1 in the names of the current element and its offspring will be changed to /Z2. Command Syntax: >-- REName --+-- ALL name name --. | | ‘-- name -----------+-->

8-8

PDMS DESIGN Reference Manual Part 1: General Commands Version 11.3

Design Database Elements

8.2.4 Locking Elements Against Alteration and Deletion Keywords:

LOCK

Description:

Locking a design element prevents it from being modified or deleted. The LOCK command allows either a single element to be controlled, or all its offspring too. (A complete Site can be locked if required.) This provides you with personal security control over your area of work. (General security restrictions affecting the whole Project are established in the ADMINISTRATION module of PDMS.)

UNLOCK

Examples: LOCK ALL The current element and all its offspring are locked. UNLOCK The current element is unlocked. Command Syntax: >--+-- LOCK ----. | | ‘-- UNLOck --+-- ALL --. | | ‘---------+-- <snoun> --. | | ‘-------------+-->

8.2.5 The Position and Orientation Attributes Keywords:

POSITION ORIENTATION

Description:

Virtually every element in the Design hierarchy has its own coordinate system which consists of a set of axes giving an origin position and orientation. The POSITION and ORIENTATION of an element are the position of its origin and the orientation of its axes relative to its owner. On creation, an element starts with the position E0 N0 U0 (i.e. at the origin of its owner) and is orientated with its axes aligned with those of its owner. The commands which alter position and orientation are all the element placement, connection and routing facilities described elsewhere in this manual.

8.3.1 Going to the Previously Accessed Element Keywords:

SAME

Description:

SAME takes you to the element you were at before you accessed the current element. Repeating the SAME command has the effect of moving repeatedly between two items - it does not move back along the list of items accessed. (If the previously accessed element has been deleted, the next available element in the list will be accessed.)

CE

CE takes you to the current element itself. (This facility may seem rather pointless in this situation; however the CE keyword is used in many commands as a means of identifying an element to be the object of that command.) Examples: CHECK CE Check the current element for data inconsistencies. ADD CE Add the current element to the display. Command Syntax: >-- CE --> >-- SAMe -->

8.3.2 Going to an Implied Tube or Rod Keywords:

IARRIVE

Description:

You can navigate to implied tube or rod within a branch or hanger (although if the derived length is less than 1mm, the system does not consider it to exist).

ILEAVE

HEAD

TAIL

TUBE

ROD

To make an implied rod or tube the current element, you must also indicate whether the head, tail, arrive or leave tube or rod is intended. Example: IARRIVE TUBE OF /PIPE1 Go to arrive of implied tube of /PIPE1.

8.3.3 Ascending the Design Hierarchy Keywords:

OWNER

Description:

Moving up the hierarchy involves fewer decisions than moving downwards, as any element can have only one Owner. Two commands (OWNER and END) allow you to move up to the immediate parent.

END

END differs from OWNER by allowing you to return to a Group element from which the current element was accessed. As the Group does not own that element, the command OWNER would go to the element’s true Owner and not the Group. You can move up the hierarchy by more than one level by inputting the type of element you want to access. For example, navigation from an Elbow to its parent Zone would involve three successive END commands. However the command ZONE would scan up the hierarchy to find the Zone which owns the current element list, thus saving two END commands.

8.3.4 Other Navigation Commands Keywords:

FIRST END

Description:

Navigate to the specified position in the members list. Most can be used with the OF keyword to go to members of other elements.

LAST TYPE

NEXT

PREVIOUS

MEMBER

Examples: FIRST BRANCH OF ZONE /Z25A LAST NOZZLE OF PREVIOUS 3 EQUIPMENTS FIRST ZONE OF /SITE 5 PIPE 2 OF /Z100A ELBOW 1 OF NEXT BRANCH

Setting a Synonym for an Element Name

Keywords

SETSTAR

Description

To save repeatedly typing an element's name, you can define the asterisk or star symbol (*) to represent any specified element. By default, if no element identifier is given, the current element is assumed. After setting, the * symbol may be entered in any command to represent the full name of the element.

Examples: SETSTAR

* will now represent current element

SETSTAR /element_name * will now represent the specified element Command Syntax: >-- SETSTAR --+-- --. | | ‘-----------+-->

Error Messages This chapter lists error messages specific to DESIGN. These messages have a message number beginning with 61. Any other messages that may be output are not described here as they are not specific to DESIGN. Note that in the following element_identifier denotes an element name or (for unnamed elements) an element reference number. The latter is a ‘system’ number which is assigned automatically whenever an element is created.
