Cant import NURBS from mayaBin or FBX

Hey I made a temple (yes,from the PDF tutorial) in Maya 2010. When I imported the exported FBX or Maya-bin into unity i dont see any of the NURBS. The NURBS make up the roof. It consists of torus and a NURBS sphere.

Any way this can be solved?

unity don't support NURBS.... convert to polygons or mesh.
