Hi Garet,

Nope, I didn't do anything to the model, I just opened up the IGES file you had posted and re-exported it to STEP format.

There is not any general special term in these file formats for "convexity points" - that's some kind of error that's specific to Alibre or its geometry library and so I don't really have any information that I can give you myself about that kind of error, you will probably need to contact Alibre to get more information about what that means and what might be done to avoid it.

I did test that step file going into ViaCAD ok, which uses the same geometry library as Alibre so I would have thought it would also go into Alibre... Here I've attached an .sat file saved out from Alibre, maybe that will go in ok since it's in the ACIS geometry library's native format.

Also does doing copy/paste like Brian mentions above work for you?
