I'm trying to simulate the motion of a 6DoF robot arm and I'm having some issues around using some assembly mates to rotate part of it. If a change a single mate over a few seconds it works perfectly fine but as soon as I try to change the rotation/distance of another mate it doesn't work any more. When I choose to filter the animated parts, nothing seems to be moving after the first few milliseconds. I've got no idea as to what is happening here and any guidance would be appreciated.
(FYI, I'm currently using SW 2014 BUT the model itself was made with SW 2012.)
