Hey Wayne,
THe file appears to be constructed with "Vetric" definitions and not so much native OpenNurbs...?
Did you possibly do the file exporting in Vetric and not Rhino or MoI?

Not sure whats going on with the 3dm file

Hi Wayne, it looks like your hex_paper_frame.3dm file isn't a Rhino .3dm file, it looks like it is some other kind of file with the wrong file extension on it.

Looks like it's from Vectric?

Michael and BurrMan,

Oops. Yes, Vectric is my CAM export program.
Mouse clicking too fast.
Sorry about this.

Wayne
