Hi Sampat,
I've done what you suggested, and it seems to work, I can now define the sphere as rigid with no "?" on geometry on the tree.
But now, although the individual components have share topology (see figure below with the exploding view), Mehcanical is creating contect between the parts of each component, which in my understanding should not be created if these parts have shared topology. This makes the nodes between the parts not coincident. Any thoughts on that?
