The LENGTHEN command ('LEN' from acad.pgp) functions in a very similar way to the TRIM and EXTEND commands, while offering more precision control of the resulting values. Starting the LENGTHEN command prompts with these options:
- DElta: Specifies the amount to lengthen an object. Can also accept an [Angle] argument when modifying arcs.
- Percent: Specifies the percentage of the length that will remain after selecting an object. Values less than 100 will shorten an object, while values greater than 100 will lengthen an object.
- Total: Specifies the total length of an object after completion of the command. Can also accept an [Angle] argument when modifying arcs.
- DYnamic: Allows dynamic lengthening and shortening of a object.
The capital letters in each option indicate the letters needed to define a option (e.g. Entering: 'DY' at the prompt will select the dynamic option). After selecting the type of lengthen operation, selecting an object will apply the appropriate change to the object. The endpoint closet to where you select an object determines how the object is modified.
HINT: Negative values can be entered for DElta to shorten an object.

AutoCAD is used by professionals world-wide to create the drawing files that define the buildings, equipment and products we use every day.New AutoCAD users struggle with the many ways in which they can enter points in AutoCAD. You can type them (3,4), you can click your mouse to select them, you can use Object Snaps to pick up points on existing geometry (hold down the shift key and right-click to see the Osnap menu).For more information visit Auto Cad
I used auto-Cad as part of learning about CAD CAM (computer aided design, computer aided construction) at school over 10 years ago. Its a very good programme.
