DELETESKETCHFEATURE command
Deletes the sketch features and their corresponding solids.

Description
Allows you to delete sketch features and all their dependencies.
Note: The EXTRUDE, LOFT, SWEEP, and REVOLVE commands and their children features SUBTRACT, and UNITE, create Features when the CREATESKETCHFEATURE system variable is ON. They are available in the Mechanical Browser panel (for example, Extrude_1, Loft_1).
Method
