Hi all, Im modeling an automobile with Maya 7.0 and have run into a problem. When I try to convert polygons to subdivisions I encounter an error. The script editor suggests that I use the Cleanup command because of non-manifold surfaces. I have tried that and the surface fo the car becomes a series of wierd circular subdivisions where the subdivisions are not atached. I also tried merging all or the vertices. Any suggestions how to effectively convert from polygons to subDs while maintaining the seams between the subdivisions.
