Sure you can. I have done it many times.
I convert the mesh to a polysurface model. You will now have a triangled patch work of surfaces for the model. Next Explode the surfaces into individual ones.
Thats it. Your done. Iges it out and read it in.
Also, you can try to export the mesh as an STL, I think MC can read that in. Or, Look on the Rhino web site. They now have a plugin for the conversion from Rhino to MC.
