Command Preview
In AutoCAD you can preview and evaluate the potential changes of many editing commands. Watching the visual cues in AutoCAD reduces the number of extra clicks and the need to undo unexpected results.
What is Command Preview?
Command preview is a productivity tool that provides real-time feedback for the active editing command. A preview of the possible outcome of the command is displayed, allowing you to make changes or correct errors before completing the command.
The following 2D editing commands support interactive preview:
- BREAK
- CHAMFER
- EXTEND
- FILLET
- LENGTHEN
- MATCHPROP
- OFFSET
- TRIM
Turn Command Preview On
By default, command preview is turned on.
- Right-click in the drawing area and select Options.
In the Options dialog box, Selection tab, select Command preview.
