Gosh, I'm kind of surprised to hear you scratching your head (glad we're on the same page at least understanding the problem), it seems like such a simple need, one encountered many times over before. I'd like to try at least connecting one null object to mesh 1, the corresponding null to mesh 2, and snap aligning the two nulls. I can then attempt, according to your suggestion, rotating one mesh from that locator against the second mesh and see how far I get, use two panels, one to grab onto the rotation, the other ever more close up on the far end of the mesh to see how close I'm getting. It would appear quite cumbersome to incrementally rotate on all three axis little by little to hone in on final registration. Seeming I have many meshes to align, there must be an elegant solution. For now, I'm thankful if you can advise me how I attach my null object to lock to a mesh at its location. Do I select the closest vertice on the mesh and do something with it that allows me to constrain the null to that point? Thanks, again.
