2008 - MarkPoint
This subassembly is used to mark an existing point on the assembly with a name.
This is usually done so that other subassemblies can later insert links that attach back to this point (for example, LinkToMarkedPoint). The attachment point is the point that is marked. You can add user-defined point codes to this marked point.
How about clearly adding the Rules and Behavior of the little gem in the Help file for it?
Like the fact that the Marked Point and the object looking for it must be attached to the same Assembly 'baseline' or offset group, and that it will not cross over the Centerline?
