Hi Steve, I'm pretty sure that there aren't any formatting problems in MoI's IGES export.

If you have an export that seems to be formatted incorrectly, can you please send me an example file so I can examine it and forward it to HarmonyWare if there are any problems in it?

Unfortunately it has just always seemed that ACIS based modelers have had some difficulties in data imports, that is not really a new thing. From what I've seen in the past, the ACIS kernel has some extra requirements on the kind of surfaces that it likes to use, it doesn't really like fully general surfaces it likes them to be parameterized in a certain particular way.

It's possible you may have better luck with SpaceClaim, I think that they have put more effort into file imports recently and particularly 3DM imports.

It won't be too far into v2 until I add in STEP and SAT format support as well, maybe ViaCAD has better support for those formats.
