Hexapod / Stewart Platform Assembly issues

Question asked by Y. Denys on Feb 27, 2013

I'm building Stewart platform and can't get it to mate properly in the assembly. All of my mates are "coincident" mates and I use points. Thus, the point on the end of the rod is mated to the point on the platform.

 

Everything is fine up to the 5th cylinder. When I introduce 6th cylinder and try to mate it, everythings goes haywire and it becomes over defined. Have anybody tried modeling Hexopod befor? How did you go about the mates?
