* Reject ambiguous origin and construction plane names * Reserve origin plane names for construction planes; suggest the other alias A construction plane can no longer be created with or renamed to XY, XZ, YZ, Top, Front or Right, so a plane argument can't become ambiguous in new designs. For older designs that already hold such a plane, the ambiguity error now also names the origin plane's other alias (XY for Top...). The existing tests build those legacy names directly.
