This sounds like a tricky area.  As I recall, in DesignWorkshop we exploit the particularities of trimesh data structures in detail.  We were driven to push this area because major performance differences forced the use of trimeshes when meshes would conceptually have been much more appropriate.  

But we should check the details to be sure.
