nurbs IGES export from max

[dileja]

Hello all, working on cnc for some mold for the plastic bottle. Bottle is designed in 3ds max, its quite complex, with some organic ornaments, leaves etc. Surface is a bit concave here and there, but not enough concave to make it difficult for pulling the bottles out of mold. I made pure nurbs surface in 3ds max, used the original mesh just as reference, no converting was done, it looks great, has no gaps, its one single independent surface. I have little experience with IGES file format, and im wandering if that kind of nurbs surface (not coverted mesh or something, pure nurbs, single surface) would be exported correctly into IGES for cnc milling.
Thanks in advance.

P.S. sorry for bad english and sorry if i posted something what already exists, simply had no time to search around.
