Undo/Redo
AutoCAD keeps a running history of all the commands you’ve issued within a single drawing session. This allows you to back up to any point in the drawing session. The UNDO command will take you back through your drawing session, one command at a time, all the way back to the start of your drawing. If you go back too far, the REDO command will move you forward, one command at a time, until you’ve restored everything.
