I am having a weird error with some simple shade geometry, and I wonder if anyone might be able to diagnose the problem or give me some suggestions as to how to fix it?
The shade surface in questions is a roof, a simple Brep in Rhino, but it gives me some very odd 3D lines at the diagonals when converted to an HB-Shade?
The lines sort of go in 3d up off the main roof for some reason?
The Brep geometry seems pretty clean from what I can tell? I guess it does have something of an ‘inside’ corner, but have never seen that cause an issue like this before? I’ve attached here an internalized / cleaned copy with the problem face highlighted for reference.
Any suggestions are much appreciated!
