Hello.
I ask you a help to understand why I can't create a solid from these surfaces.
I don't understand why open edges are being reported that seem to be lines.
Now I don't have a rhino in my hand and I go to memory
is a long and narrow surface on the side of the van about half height
I solid edge don't know it but in step you can export it even if it's not a solid, maybe there's some kind of command the solid works create that could solve these problems
