24 Chapter 1: Getting Familiar with AutoCAD
when you neeD to unDo
The AutoCAD User Group International (AUGI) has conducted a survey to identify the most
commonly used features in AutoCAD. The group found that the Undo feature and the Esc
key were at the top of the list. Everyone makes mistakes, and it would be impossible to get
any work done if it weren’t for these two features. But Undo and the Esc key are just two of
a set of features you can use to reverse something you have done. If you find you’ve done
something unintentionally, you can use the following options to get out of trouble:
Backspace If you make a typing error, press the Backspace key to back up to your error, and
then reenter your command or response.
Esc When you need to exit a command or a dialog box quickly, without making changes,
just press the Esc key in the upper-left corner of your keyboard.
U↵ If you accidentally change something in the drawing and want to reverse that change, click
the Undo tool (the left-pointing curved arrow) in the Standard toolbar. You can also enter U↵ at
the command prompt. Each time you do this, AutoCAD undoes one operation at a time, in
reverse order. The last command performed is undone first, then the next-to-last command,
and so on. The prompt displays the name of the command being undone, and the drawing
reverts to its state before that command. If you need, you can undo everything back to the
beginning of an editing session.
Undo If you decide that you want to back up a few steps in an operation you just performed,
you can use the Undo tool (the left-pointing curved arrow) on the Quick Access Toolbar.
Each click of the Undo tool steps you back one operation.
Redo If you accidentally undo one too many commands, you can redo the last undone com-
mand by clicking the Redo tool (the right-pointing curved arrow) on the Quick Access Tool-
bar. Or enter Redo↵.
If you’ve used earlier versions of AutoCAD and are wondering where the Undo and Redo
drop-down lists went, you can find them by opening the Standard toolbar. Right-click the
Quick Access Toolbar, and select Toolbars
AutoCAD
Standard. The Undo and Redo
drop-down lists enables you to be more specific about the point to which you undo or redo
your work.
