Sometimes you will want to stop an action that you have not yet finished, or undo the last change you made. If you change your mind after undoing an action, you can redo it.
Use the ESC key to interrupt an action before you complete it.
Use Undo to reverse an action, or event, that you just completed (keyboard shortcut CTRL+Z). You can undo up to 100 of the last events, depending on the undo event limit setting.
| Undo and Redo affect only actions that have occurred since the last time you saved the drawing. For example, if you move an object and then save the drawing, you cannot undo the move. |
