Hi Marc,
The 2D boundary structure is really messed up. Do you recall how it was created?

It was part of an object imported from CATIA v5 through the DATAKIT Rhino plug-in.

It would be great if you can report this to DataKit. Meanwhile, if you haven’t already figured out how to get around it, you can call DupBorder and PlanarSrf.

Thanks,
Chuck
