Basic commands - ll
The previous lesson dealt with drawing commands. This lesson will introduce some common modifying
commands. In AutoCAD, you may actually use modifying commands more often than drawing
commands. Now that you know the basics, here’s some more commands to add to your collection. Three
commands, Trim, Extend and Offset are used often in 2D AutoCAD work.
Command Keystroke/Short cut Location Result
Rectangle RECTANGLE/REC Home>Draw>Rectangle Draws a rectangle after you enter one
corner and then the second.
Trim TRIM/TR Home>Modify>Trim Trims objects to a selected cutting edge.
Extend EXTEND/EX Home>Modify>Extend Extends objects to a selected boundary
