Sub d complex structure wont make 2d

Rhino SubD
1

Hi,
I have made some complex curves with sub d surfaces. I have added a clipping plane to these and I’m now trying to make 2D. My 2d shows up empty and I don’t know why its not working. I uploaded some pictures of what I’m trying to make 2d and what I get when I make 2d.

Hi -

It’s hard to tell what’s going on in pictures like that. Please post a 3dm file.
Apart from that, as per RH-56154 it is expected that the Make2D result of a SubD object might have issues. You could use the ExtractRenderMesh of such object and use that in Make2D.
