4.21 LENGTHEN Modify ► Lengthen This command can be used to check or change the length of an object. Command:LENGTHEN Select an object or [DElta/Percent/Total/DYnamic]: Select one option inside the square bracket to change the length
If you select an object without selecting any option AutoCAD show you the current length of that object or the included angle. To change the length or angle, you must select one of the options.
2D construction Cont… SOLID This command creates solid-filled triangles and quadrilaterals. Command: SOLID Specify first point: Use one of the point fixing method Specify second point: Use one of the point fixing method Specify third point: Use one of the point fixing method Specify fourth point or <exit>: Use one of the point fixing method
The first two points define one edge of the polygon. The third point should be specified diagonally opposite to the second point and then specify fourth point. When there is a continuous sequence of regions to be filled, the same can be done in a single SOLID command. AutoCAD takes the last two points from the first region as the first two points for the next region. P3 P3

DONUT Draw ► Donut This command draws filled circles and rings. Command: _donut Specify inside diameter of donut <0.5000>: Specify a distance Specify outside diameter of donut <1.0000>: Specify a distance Specify center of donut or <exit>: Use one of the point fixing methods Specify center of donut or <exit>: Use one of the point fixing methods or press

PLINE Draw ►Polyline You might have drawn several line segments using a single LINE command. But AutoCAD treats each line segment as a separate object. Each segment can be edited separately. PLINE command lets you draw line segments, but from start to end, it is treated as a single object. Command: _pline Specify start point: Current line-width is Specify next point or Specify next point or Specify next point or
0.0000 [Arc/Halfwidth/Length/Undo/Width]: fix the point [Arc/Close/Halfwidth/Length/Undo/Width]: fix the point [Arc/Close/Halfwidth/Length/Undo/Width]: fix the point
Construction Lines Construction lines are used in the drawing as the reference lines for creating other objects. There are two main line types namely RAYs and XLINEs.
RAY Draw ► Ray RAYs are particular construction lines that start from a point you specify and goes to infinity. Command: _ray Specify start point: Use one of the point fixing method Specify through point: Use one of the point fixing method
XLINE Draw ► Construction Line XLINE is a linear object, which starts at infinite and ends at infinite, or we can say that it is a line, which has no end point but passes through a specified point. These lines are used fir projections. Command: _xline Specify a point or [Hor/Ver/Ang/Bisect/Offset]: Use one of the point fixing method or enter an option Specify through point: Use one of the point fixing method or
Display Control Commands Zoom View ► Zoom ► [options] This command enlarges or reduces the view of the drawing. When we are working on a drawing it is always required to bring the area of our interest to focus on to the screen. Command: ZOOM Specify corner of window, enter a scale factor (nX or nXP), or [All/Center/Dynamic/Extents/Previous/Scale/Window/Object]
time>:
Enter

PAN View ► Pan ►Real Time/ Point / Left / Right / Up / Down This command allows you to move the drawing without changing magnification or dimention Command: pan Press ESC or ENTER to exit, or right-click to display shortcut menu.
REGEN View ► Regen Regen regenerates the entire drawing and recomputes the screen coordinates for all objects. Regen command used to make curves smooth after zooming. If the REGENAUTO feature is enabled, regeneration will be performed automatically.

5.0 Create and Manage annotation in AutoCAD 5.1 TEXT Draw ► Text ►Single Line Text Text conveys the meaningful information in your drawing. We use text for title blocks, to label parts of the drawing, to give specifications, or make annotations. You can format text as Command: _text Current text style: "Standard” Text height: 0.2000 Specify start point of text or [Justify/Style]: Use one of the point fixing methods or enter an option Specify height <0.2000>: Enter a positive value Specify rotation angle of text <0>: Enter an angle
Start point
5.2 MTEXT Draw ► Text ►Multiline Text… Text in the form of paragraphs, can be effectively generated in AutoCAD with this tool. The userspecified text boundary determines the width of the paragraph and the justification of text within the paragraph. Each multiline text object is a single object, regardless of the number of lines it contain. Command: _mtext Current text style: "Standard" Text height: 0.2000 Specify first corner: Use one of the point fixing methods Specify opposite corner or [Height/Justify/Line spacing/Rotation/Style/Width]: Use one of the point fixing methods or enter an option
After you specify the second corner, AutoCAD displays the Multiline Text Editor Dialog box. The Multiline Text Editor includes a Text formatting toolbar and a shortcut menu.
5.3 STYLE Format ► Text Style… STYLE command is used to create user defined text styles.
AutoCAD provides a default text style called STANDARD. Users can define their own text style by choosing a font from the listed font files and applying the desired effect such as width factor and oblique angle.
5.4 TABLE Draw ► Table… The TABLE command opens the insert table dialog box.
Then you can create a table according to your preference.
If you select an object without selecting any option AutoCAD show you the current length of that object or the included angle. To change the length or angle, you must select one of the options.
