Plugin to convert fairly high files of quads to nurbs?

Does anyone know if there is a plugin or stand alone that can handle a fairly large quad file and convert it to nurbs? I recently saw CreateQuadMesh but it doesn’t look like it can go from quads to nurbs.
Mesh2Surface I wasa given a demo from one of my ZBrush files but it didn’t look really good.

Maybe Cyborg3d … have used their SolidWorks plugin but not this stand alone version.
