Rhino to VRED

Does anyone here have any tips for sending models from Rhino 5 to VRED? I’d like to be able to tag surfaces and polysurfaces with some kind of identifier (either text, or colour, or both) to make it easier for the guy at the other end to assign materials for visualisation.

From what I’ve read, VRED converts NURBS to triangular meshes upon import. Is this correct?
