One of our customers brought up a very interesting problem recently. What he wanted to create was some structural reinforcement inside of a sheetmetal fabricated arm. He wanted to have a toothed shaped feature that would interact with and be welded to the sheet metal as an internal reinforcement, but creating the part interface manually could be quite time consuming. Rather than do it manually, we tried out creating it as a multibody part that we split up after the fact.
