What Is the Difference Between Undo and Redo in AutoCAD?

When working with AutoCAD, it’s essential to understand the difference between the “Undo” and “Redo” commands. Both of these commands play a crucial role in the design process and can save you time and effort when used correctly.


The “Undo” command in AutoCAD allows you to reverse your previous action or series of actions. It acts as a safety net, enabling you to fix any mistakes or unwanted changes made to your drawing. With a simple keyboard shortcut or by selecting the “Undo” option from the toolbar, you can step back in time and undo your most recent action.

For example, let’s say you accidentally deleted a line that was an important part of your design. Instead of manually redrawing the line, you can use the “Undo” command to restore it instantly. This command is particularly useful when you want to experiment with different design options but need the ability to revert back quickly.


The “Redo” command in AutoCAD is the opposite of “Undo.” It allows you to reapply an action that was previously undone using the “Undo” command. By pressing the keyboard shortcut or selecting “Redo” from the toolbar, you can bring back any changes that were undone.

Let’s say after using the “Undo” command, you realize that deleting that line wasn’t actually a mistake, and you want to restore it again. Instead of redoing all your previous actions manually, simply use the “Redo” command to bring back that deleted line instantly.

Using Undo and Redo Together

The combination of these two commands provides a powerful way to navigate through your design history. By using them together strategically, you can experiment freely while having control over every change made to your drawing.

For instance, if you want to test different design options, start by making a change and then use the “Undo” command to revert back. Next, try another option and repeat the process until you find the desired outcome. If you decide to go back to a previous version, simply use the “Redo” command to step forward in your design history.

Keyboard Shortcuts

To make working with “Undo” and “Redo” even more efficient, AutoCAD provides keyboard shortcuts:

  • Undo: Press Ctrl + Z
  • Redo: Press Ctrl + Y

By memorizing these shortcuts, you can quickly navigate through your design history without the need to search for these commands in the toolbar or ribbon.

In Conclusion

The “Undo” and “Redo” commands are invaluable tools when working with AutoCAD. Understanding their differences and knowing how to use them effectively can enhance your productivity and save you valuable time during the design process. Remember to take advantage of keyboard shortcuts for even faster access to these commands.

So next time you’re working on an AutoCAD project, don’t hesitate to experiment with different ideas and designs, knowing that you have the power of “Undo” and “Redo” at your fingertips!
