I haven't been keeping up with AutoDesk products but:
I think the problem you are having with "Good" IGES files is:
the creator
the complexity of the geometry
not using true SOLIDS
I was under the impression that AutoCAD creates wireframe based geometry
(like chicken wire). It is not a TRUE SOLID geometry representation,
they say its a solid but....
I've also heard that Mechanical Desktop latsest version works in solids.
I would create it in Mechanical Desktop, Pro-E, SolidWorks, or other
solids based programs and see if you get different results.
