CHAPTER 1 GETTING FAMILIAR WITH AUTOCAD

When You Need to Undo

Recently AUGI, the AutoCAD User Group International, conducted a survey to identify the most com-

monly used features in AutoCAD. They found the Undo and Escape keys were at the top of their list.

Everyone makes mistakes, and it would be impossible to get any work done if it weren’t for these two

features. Undo and the Escape 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 some of 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 retype your command or response.

Escape (Esc) When you need to quickly exit a command or a dialog box 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 in the Standard toolbar (the left-pointing curved arrow). You can also type U

↵ at the Com-

mand 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 dis-

plays the name of the command being undone, and the drawing reverts to its state prior to that com-

mand. If you need to, 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 of an operation you just performed, you

can use the Undo tool (the left-pointing curved arrow) in the Standard toolbar. Or type Undo ↵.

Each click of the Undo tool steps you back one operation. In AutoCAD 2007, you can also select the

exact command to undo by using the Undo drop-down list. You can open the Undo drop-down list

by clicking the downward-pointing arrow found to the right of the Undo tool.

Redo ↵ If you accidentally Undo one too many commands, you can redo the last undone command

by clicking the Redo tool (the right-pointing curved arrow) in the Standard toolbar. Or type Redo ↵ .

In AutoCAD 2007, Redo allows you to redo several operations that you might have undone with the

Undo command. You can also select the exact command to redo by using the Redo drop-down list. To

open the Redo drop-down list, click the downward-pointing arrow found to the right of the Redo tool.
