This may be a stupid question, but how do I constrain a point on a solid, for example at the center of the circular end surface, and then have a rigid link between the point and the rest of the surface.

I.e. I want the center of the rod end to have fixed translation and free rotation in all directions, and the point rigidly connected to the rest of the surface.

In Creo Simulate, I would have created a point constraint (fixed translations, free rotations), and then a ridig link between the point and the surface. Is there any way I can do this in Solidworks Simulation?
