exporting styles via .obj

 From:  the_captain (JOHNZAPF)
Hi there, I'm importing dwg drawings into Rhino from ACAD and then saving to 3dm format so I can export the models I receive via obj and bring them into c4d. Moi does a nice job of ngons. Is there a way to preserve the style or layer hierarchies when importing into c4d or something like that? Such as an option to group those objects together?

Maybe someone has come up with a script for exporting separate styles as separate files.

Thanks much
