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.
EXERCISE 2-6 USING UNDO/REDO
From the Quick Access toolbar, choose Undo (or press <Ctrl>+Z). The lines created with the previous LINE command will disappear. Look at the command prompt, and see that the lines were undone. The Redo button is now active in the Quick Access toolbar.
Choose the Redo tool. The lines will reappear.
Choose the Undo tool until all the lines are gone (model space is empty). If you go back too far (for example, back into paper space), use the Redo tool to get back to an empty model space.
Save your drawing.
