Entity Draw Commands in AutoCAD
Line Command The LINE command lets you draw straight lines. You can specify the desired endpoints using either 2D
or 3D coordinates, or a combination of the two. If you enter 2D coordinates, AutoCAD uses the current elevation as the Z component of the point.
Format: From point: To point: To point:
LINE Enter a point. Enter a point. to end line sequence. 4

Entity Draw Commands in AutoCAD
Line Command To erase the last line segment without exiting
the LINE command, enter "u" at the To point: prompt. You can constrain lines to horizontal or vertical by using the ORTHO command. Relative, cylindrical, and spherical coordinate point entry is allowed. You can also use object snap to specify particular points -- endpoints of lines, centers of circles, etc. -- of previously drawn entities. 5
CAED - Chapter No 3
Entity Draw Commands in AutoCAD
Drawing Lines To draw single-segment and multiple-segment lines:
1.
2. 3.
4. 5.
Choose Line from the Draw menu, then choose Segments. Using the mouse, click a point on the screen. Move the crosshairs to a second point on the screen. As you move the crosshairs, a rubber-band line shows you what the line will look like. Click on the second point. To end the line at the second point, press the right mouse button (this is the same as pressing ).
If you want to continue the line, keep clicking points on the
screen. AutoCAD draws additional lines, each starting at the endpoint of the previous line. When you are done, press the right mouse button. 6

Line Type The LINETYPE command sets the linetype for new
entities. It can also load linetype definitions from a library file, write new definitions to a library file, and list the linetype definitions in a library file. You can control the dot-dash linetype of each entity individually, or by layer.
Format: LINETYPE ? / Create / Load / Set: ? 8
CAED - Chapter No 3

Line Type To change the linetype of existing objects, use the
CHANGE command. To control layer linetypes, use the LAYER command. Options ? Lists the linetypes defined in a specified library file. Create Allows creation of a new linetype and stores it in a specified library file. Load Loads selected linetypes from a specified library file. Set Sets the current linetype used for newly drawn entities. 9

Point Command The POINT command lets you place a Point entity in the
drawing. Points are useful as "nodes" for object snap purposes. The appearance of Points in your drawing is governed by the PDMODE and PDSIZE system variables.
Format: POINT Point: Designate a point.
You can enter the DDPTYPE command to view the
various forms a point can take. 11
CAED - Chapter No 3
Entity Draw Commands in AutoCAD
PDMODE PDMODE is a system variable that stores the display
mode for Point entities. The value stored is an integer and is saved in the
drawing file. When you enter the POINT command, AutoCAD
draws the Point entity in the form specified by PDMODE, and at the size specified by the PDSIZE system variable. 12
CAED - Chapter No 3
Entity Draw Commands in AutoCAD
PDMODE Options
0(Default) A dot at a point. 1Nothing. 2A cross through a point. 3An X through a point. 4A vertical line upward from a point.
To each of these values you can add 32, 64, or 96 to set a
figure to be drawn around a point. + 32 Draws a circle around a point. + 64 Draws a square around a point. + 96 Draws a circle and square around a point.

PDMODE Therefore, there are 16 valid PDMODE settings:
0 1 2 3 4
32 33 34 35 36
64 65 66 67 68
96 97 98 99 100
Note:
All Points are redrawn to the form currently specified by PDMODE when the drawing is regenerated. 14

PDSIZE PDSIZE is a system variable that stores the display
size for Point entities. The value stored is a real number and is saved in the drawing file.
By default, AutoCAD displays Point entities as a single
pixel.
If PDSIZE is set to a positive number, it specifies an
absolute size for Point entities. If negative, it is interpreted as a percentage of the viewport size, and Point entities retain their appearance as you zoom in and out, provided the zoom performs a drawing regeneration. 15

DDTYPE – Point Style Dialogue Box The DDPTYPE command lets you specify a new point
display mode and size. Format: DDPTYPE
When you enter the DDPTYPE command, AutoCAD
displays the Point Style dialogue box. Current values for the point display mode and size are shown. Change the point display mode by clicking the new image tile. The PDMODE system variable is updated when you exit the dialogue box. The value you specify in the Point Size edit box depends on which radio button you select

boundary. The area isn't hatched, and it's saved in your drawing. In the Polyline Creation dialogue box, the Define boundary Set area and the Ray Casting popup list are identical to the ones in the Advanced Options dialogue box used by BHATCH. When you use BPOLY, AutoCAD disables the Retain Boundaries check box. Pick the "Pick Points" button to accept the settings in the Polyline Creation dialogue box and create a Polyline.
