Danny was right with the flat circle. I cut it off flat and it shelled fine. Brian your probably like me with trying to figure out why certain things work then dont work. Shelling is a fine operation with a model that needs to be set up properly to work. Dont be discouraged that there are many different ways to do the same thing. I think for me personally I have to put more time into the design decision before I start whaling away.

Try a second approach and you may find your MoI.
