Spherical joint help


New member
Hi Guys,

I have tried so many times to create spherical joint as per drawing but always DOF=1 and i can`t find it.

i think an order still missed. On the ball, i have create only spherical joint to let the ball slide in all direction inside the inner spherical surface but still same issue.

I need your help guys and thanks in advance

Did you define an input command?

It's hard to understand the joints - could you identify the parts 1 thru 6 please, (and maybe use different colors)

Part4 (?) might be free to rotate about it's centerline. You might have to add a "dummy" joint to prevent that (or change one of the Spherical joints to a Constant Velocity joint)
