Hi maxim, so another way I could describe it is - if you want to transfer polygon mesh data out from MoI into a rendering program, then 3DM format is not a good way to do that. It's better to instead use OBJ format to transfer polygon data between programs, that's a much more common format to use for that particular kind of data.

MoI will only write NURBS data to 3DM files and does not store polygon data in them.
