Troubleshooting Convert

1. If the polygon mesh does not convert or results in a hard-to-use subdivision surface, see the Prepare a polygonal surface for conversion to a subdivision surface.
2. If the NURBS surface does not convert to a subdivision surface or results in a hard-to-use subdivision surface see the following:
   • Prepare a NURBS surface for conversion to a subdivision surface
   • Convert a subdivision surface to polygons
   • Convert a subdivision surface to a NURBS surface
   • Modify > Convert > NURBS to Subdiv, Polygons to Subdiv
