Hi Piter,

> What I made wrong?

I'm not sure - can you please post the 3DM file that you are trying to export ? The finished file I mean, not the earlier version of it. I will try it in a few other programs and see if I can see what they might be complaining about.


> And very big question about export to PROE, is there any solution this problem, plagin or other???

I'm not all that familiar with Pro/E so I don't really have a lot of advice. What specific version of Pro/E are you using?
