Display problem from inside geometry

Hi there,

I can’t see a closed surface when I’m inside of it, neither in shaded nor rendered mode. Ghosted works fine though.
I tried refreshshade but no difference. It was working fine up to some time ago. I also tried to restart rhino.

Any clue?

Hello - a closed surface or polysurface has the back faces culled - the inside does not draw. You’ll need a hole in it someplace.

Ok, thank you Pascal
