Hi Nick,

Did you also try IGES? IGES usually has surface trimming boundaries that are closer in structure to how MoI needs them, so that will not as often have that same type of trimming problems. Instead the problem becomes processing the individual surfaces to join them together, but that tends to be most difficult if you've got some tiny slivery surfaces mixed in with other ones hopefully you don't have that in your particular model.

Let me know if you are still stuck and I can try to use some intermediate steps as well.
