Hi BurrMan & Chris, if you import MoI 3DM files, the NURBs are imported directly. You will need to tell KS5 & 6 to render NURBs data. As far as i know all other NURBs formats have the option to tessellate upon import. Simple rule of thumb, if you try to import a file and KS reports a no geometry found error, the check the import NURBs data option and you should be good to go.
