Hi, I created Assembly1 using Part1 and Part2. When I inserted components Part1 and then Part2, I clicked on the green OK check mark so that the origin of Part1 (the main part) get fixed to the origin of the new Assembly1. I saved the file. Then, I created a new assembly file called Assembly2. I inserted Assembly1 into it. Again, I clicked the green OK check mark so that the origin of Assembly1 (which is also the origin of Part1) got fixed to the origin of Assembly2. So far so good.

Here is the problem. In the last step, if during the insertion I changed the orientation of Assembly1 by rotating it about the Z-axis to make it upside down and then clicked on the OK check mark to make the origin of the inverted Assembly1 (i.e. origin of Part1) fixed to the origin of Assembly2, I got the wrong origin. The origin moved outside Assembly1. Is this a bug? How do I fix it?
