RE: Autodesk / IGES problems

You are basically right, but the fact remains that there is a minimum of 100K seats of the stuff being used by companies who think that they can go directly to RP with little or no added expense. Simply not true!!!

At issue is how do we use what is already created?

Not what to use instead of XYZ software.

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.
