In AutoCAD, undoing a command typically means reversing the most recent action or stepping back through your actions in sequence. This is achieved using the standard UNDO function.
Undoing Your Actions in AutoCAD
AutoCAD allows you to easily revert the last action you performed. The UNDO command (or function) reverses the sequence of previous commands. If you've made a mistake or want to back up a step, undoing is the primary way to do so.
Using Keyboard Shortcuts
The quickest way to undo in AutoCAD is by using familiar keyboard shortcuts. These shortcuts are standard across many applications, making them intuitive for most users.
- For Windows: Press Ctrl + Z
- For Mac: Press ⌘ + Z
Each time you press this combination, AutoCAD will undo the last command or action performed.
Using the UNDO Command
In addition to keyboard shortcuts, AutoCAD also provides a command specifically for undoing actions. You can access this function by typing the UNDO command directly into the command line.
While typing UNDO and pressing Enter will also undo the last action, the keyboard shortcut (Ctrl+Z or ⌘+Z) is generally the most efficient method for single-step undo operations.
Reversing an Undo (REDO)
Sometimes you might undo something and immediately realize you didn't mean to. AutoCAD also provides a way to reverse an undo operation, known as REDO.
- For Windows: Press Ctrl + Y (or alternatively, Ctrl + Shift + Z)
- For Mac: Press ⌘ + Y (or alternatively, ⌘ + Shift + Z)
REDO reapplies the command(s) that were just undone, moving forward through your action history.
Source Information
Information regarding the UNDO and REDO commands and their keyboard shortcuts in AutoCAD, specifically Ctrl+Z/⌘+Z and Ctrl+Y/⌘+Y or Ctrl+Shift+Z/⌘+Shift+Z, is available in the AutoCAD web application Help documentation.
