I have a problem about Rhino’s display. There’re some complex meshes baked from grasshopper, but some faces of them seemed like to be clipped.
Those faces would be shown when I just changed the display mode or some other settings, but if I rotated the view or setting down, they were disappeared.
Could be a couple of things. Did you try to rebuild the mesh in Grasshopper? I would guess it hase something todo with the mesh normals, maybe check them as well
