For the purpose of tolerance and interference checking, as the end step of making a generic part I would like to have a single feature which grows the entire part or selected faces of the part by some amount. Essentially what "offset entities" does for sketches, but in 3D. A surface "offset" is almost exactly what I'm looking for, but its not a solid, and it creates gaps at sharp corners. Does SW 2017 have this functionality?

Im on Windows 10, SW 2017.
