Convert CGR to 3DM

Can you convert CGR to 3DM?
QUICK ANSWER
Is it possible to convert CGR to 3DM?
No - not a direct conversion.

Rhino's 3DM wants accurate NURBS/solids; importing a faceted CGR gives only a mesh. Possible via a mesh import but of little engineering value - convert to STL/OBJ instead.
