I have been trying to create an animation of an assembly with about 30 parts. I was trying to use the dimensions to adjust the position of the parts and it just doesn't move at all. I switched to a simple assembly with only 2 parts, one dimension change - no difference. Is there something I am missing? To change the dimension I expand the part that I want to move, find the distance mate, double-click on the diamond, set the new distance. Re-run the animation - nothing. What am I doing wrong?
You need to move the time bar and then change the distance value to get the motion working. Check attached flash file (sorry the video quality is not good)
