All text is searchable, and you can attach PDF files to your drawings for better performance. Smart Dimensioning Automatically create appropriate measurements based on your drawing context. Pass the cursor over selected objects to get a preview of the dimension—before you create it.

Minimize the need to undo an operation by using Command Preview, which lets you see the results of a command before you commit to it. Move and copy large selection sets more easily.
