[Simscape multibody] Modeling contact between revolved solid and brick solid

Hello,

I need to model the contact between a revolved solid and a brick solid. I'm using the block "spatial contact force", which I have to connet to the two solid. In order to do that I thought that the best way would be to "export entire geometry". I can do that with the brick solid but I'm not able to do that with revolved solid.

Is there any alternative to achive this kind of modeling?

Revolved solids support exporting Convex Hull which is an approximation of the revolved geometry. The convex hull is supported by the Spatial Contact Force block. The contact is then between the convex hull and the other geometry. Otherwise, the only way to do it is to approximate the revolved solid as a collection of solids that support "Entire Geometry" however that introduces many spatial contact force blocks and would likely not be better than the convex hull approach.
