Error exporting from Rhino .iges file

Rhino Rhino for Mac

Hi to everybody,
I get this message when i try to export my model into a .iges file:

I tried to recover it and checked the bad objects, also changed Rhino version and operating system, still nothing changed.

I really need it.

Many thanks!

Stefano.

You can see more status line messages by clicking the “4 bar” icon to the left of the error message. If there is nothing helpful in the additional status messages, we’ll need to get a copy of your model to determine the problem.
