A remark on asymmetric tolerances & dim/bound > middle vs. inheritance
features. As of WF2, according to the release documentation, a part can be
designed with asymmetric tolerances, and manufacturing can work on a derived
part with symmetric tolerances, derived from the first part with inheritance
