Flattens a sheet metal part in the same document as the design model. The flattened version of the part is associative to the formed version of the part.

You can use the Flat Pattern Treatments tab on the Options dialog box to control output parameters for the flat pattern. For example, you can specify that any B-spline curves in the formed part are simplified to lines and arcs when creating the flat pattern. B-spline curves can be created when creating cutouts across bends and when using stencil font characters.
