In the cascading menus, select 'Insert-->Dimension' and notice that the
'Perimeter' command is grayed out and unavailable.
Why is the 'Perimeter' dimension grayed out in the Drafting application?
Solution
The 'Perimeter' command becomes available when there is an active Sketch in
the drawing.
1. In the Part Navigator, highlight a view in a drawing sheet.
2. 'MouseButton3-->Active Sketch View'.
3. Select 'Insert-->Sketch Curve' and select a Sketch Curve command.
The sketch will become active and the 'Perimeter' command will be available.
However, once 'Finish Sketch' is selected, the 'Perimeter' command will once
again be grayed out.
