GH geometry can't make Wall From Solid

Brep and Curve internalized into GH definition can’t make Wall From Solid but the same geometries baked and referenced from Rhino works fine.

Hello Jakub,

It looks like the problem is the Brep (the curve works fine when I switch it on other components). I tried building a new Brep and internalised it and it worked fine, with the one you sent it doesn’t though. How did you create the Brep?

Honestly, I don’t remember. I was testing some stuff.
The strangest thing is that after baking and referencing it again, the same Brep works fine.


Ok, I was asking about it because if the problem is in the Brep construction, maybe there is nothing we can do about it. The Breps I built so far worked fine with the Wall From Solid component, so I cannot report the issue for the moment. Anyway, I’ll keep an eye on this issue to see if it can be reproduced again.

Hi @Czaja,

The BREP is flipped, so face normals are pointing inside the closed polysurface. Rhino fixes this issue automatically when a BREP is added to the document, but Grasshopper doesn’t.

I’m going to fix this issue in VisualARQ 2.11 so a flipped polysurface could be used as a wall shape.
