I have a very complex scan that has a lot of surface detail. I can get the whole part into a solid. What I need to do is get it shelled. I have tried shelling the part and it fails. I tried surface offset and it failed. I even began to go through and offset individual surfaces and when I get more than 2 or three individual surfaces together it fails. I imported it in as an stl and tried to use scan to 3d and still had no luck. I'm not sure where to go next. I attached the STL if anyone would care to look at it. It was also sent as Iges and step. What I am trying to do with this is split it into 2 parts along the parting line and get it injection molded in 2 pieces. Any help would be greatly appreciated.
