Re: Idea for a new functionality; Split Sheet Metal Body à la "Normal Cutout"
make the convert to sheet metal so that it checks the edge faces and makes them perpendicular depending on which side of the part you select. (inside face or outside face)
have an extra option in the Cleanup Utility that makes edge faces perpendicular to the "base faces"
