This tool deactivates one or more selected sheet metal models and causes them to be treated like any non-sheet metal solid parts. This allows you to perform post-fabrication operations on them, such as drilling at an angle through a face, welding corners, and adding form features and custom FeatureScript features.

Leaving a sheet metal model unfinished (active) causes it to be treated as sheet metal. If you do not intend to perform post-fabrication operations on the sheet metal model, the Finish sheet metal model feature is unnecessary.
