Dear all,

I have modeled two spheres that I would like to constrain to each other. The first sphere is fixed and the other one shall be able to rotate around the first one in all directions (x,y,z) but within limited angles. They shall have the same centre of rotation.

I started by making the origins coincident. I constrained the planes of the spheres under advanced mates with a limited angle (ex; angle 0, max angle 120, min angle -20). First two planes works fine but when I try to constrain the third plane I get an error message saying that the constrain cannot be solved or that the assembly will be over constrained. What shall I use instead? Is there another way of doing this?

When I have succeeded with constraining I will connect a rod to the sphere that can be rotated. It is really important that the rod can be rotated within specified angles only.

Best regards,

Jenny
