Hello, I've noticed in both NX 10 and NX 12 that the assembly arrangements are having strange behavior. I created different arrangements that have doors in a cabinet. For some of the arrangements, the doors are open and in others, the doors are closed. I have the doors constrained by angle constraints. For quite a while, I'll be able to select the Open arrangement or the Closed arrangement and everything will be fine. Then, all of a sudden, I'll open up the Open arangement and the door is going through the cabinet instead of swinging 90 degrees out like it should be. What would cause this to change? I don't believe I made changes in this assembly for a long time, so I have absolutely no idea why this junks out. I've noticed this behavior in both NX 10 and 12. I'll reset the arrangement and eventually it will junk out again. Maybe it's a related thing to the problem of NX of assembly constraints that I and others have commented about. I have no idea. Thanks
