Good evening,
I am trying to create an animation of my CAD but I have a problem when I am in Mechanical Systems Design. When I try to create a command, the Mechanism Manager tells me that I have too much DOF (I have 1) and I don't get any commands. I made again my assembly in order to get as few mechanical connections as possible but I still have the same issue. Can anyone help me?
Thank you in advance
