Polygons with wrong orientation in my Solibri not visible.

[m.neustadt]

Got a 3d staircase from Vectorworks in an ifc-file. Somehow on my computer with my installation some polygons are “transparent”. On other computers everything works fine.

Got a MB Pro 16" with AMD Radeon Pro 55000M, 8GB VRam, 16GB Ram, 2.3 GHz Core i9 CPU, actual Big Sur 11.7.1 OS. So, not thaaat bad. (could be better, but, still more than sufficient)
Deleted all user and machine library stuff called “Solibri”, reinstalled Solibri, no change.

(the broken view screenshot is on my machine of course, it’s the SAME IFC FILE)!!!

Did you compared the (3D) settings?

maybe on one machine the "Show Component Edge Lines are on and on the other machine off?
