I'm working in an assembly and I have a component that has a couple of threaded holes. There is another part that is supposed to mount to this component and has clearance holes to mount to the threaded holes. On the part with the clearance holes I sketched on the surface and focus off the two center points to locate the clearance holes. Now if I move the compontent with the clearance holes within the assembly the two holes always lines up with the threaded holes. This is not supposed to work like this as I've done this same operations millions of times in SCRC, NX and Pro E. The only time the clearance holes is supposed to move on the part is if the threaded holes is repositioned not if I only move the component around in the assembly.

Does anyone know if this is a bug with SW2010 Premium? I'm attaching the two parts. The Green is fixed and the Purple if moved up and down the holes does not with the part and tries to line up with the original holes.
