I have redesigned a repeated part of a larger object, and as a result, had to delete several instances of the "same" vertices. now, I can use
D to make a dupe of the corrected vertex group, but I only get translation control, scale control or rotational control. And in rotational control only Cursor, View, Gimbal, Normal, Local and Global are available, yet the obvious ones of Cursor, Global, and Local only rotate around the same axis of the part:
However, I need to rotate around the little "orange dot" demarking the item's origin point.
