I am trying to make a simple Generic Annotation family (a photo marker) with an arrow that rotates based on an angle parameter. My expectation is that I should be able to either: Group a set of lines (the arrow) and lock that group to a rotating reference line. Nest a family (the arrow) and easily lock it to a rotating reference line. The current method is extremely difficult, buggy, and non-intuitive. When I try to lock a group, the lines distort. When I nest a family, it fails to rotate or requires a complex, hidden workaround. Please provide a simple, robust way for 2D geometry (lines, groups, or nested components) to be locked to a reference line and rotate with it as a single, rigid object when an angle parameter is changed.
