Nurbs to 3D print surface quality

Hey all,

When I export from Moi and import to my slicer app (S3D and Cura) my surfaces are faceted. Ive tried to increase the polycount but I end with a much larger file with narrow facets (still no smooth surface). Any tips on how to get the same surface quality I get in MOI to a 3D print? 3rd party apps? scripts?

-Thanks!
Alan
