Thanks a lot for the fix, of course I'll report any other bug I found in the next release.

I'll try to rebuild this model with the next beta, I wasn't able to finish the model in nurbs (nothing to do with the export bug), but
the method I used wasn't good ... So I switch to modo for this one.



I really don't know which approch I have to used for something like that. I've tried to build the model in full flat (planar) face first, but then can't fillet anything.
It's strange how simple model at first can be hard to build ...
