More than likely you have multiple poly's present that are exactly on top of each other but yet already hinged off the same vertex. Select the entire mesh, then select weld and set the tolerance to a small value. This will weld ALL overlapping points and elminate duplicates. It's possible that some things will change. If all your ploys are triangles, I think you should be able to then select the entire mesh and fill polygons. Shouldn't be too much trouble. Remember to also select the whole thing and crease all your edges. -Kix
