Visualization rule 234: odd triangles

[akaas]

Hello everyone,

I’m using rule 234 to check whether prefab elements correspond to architectural design.

I’m getting odd visualization behaviour in the 3D window, when viewing the checking results. The inner component (as distinguished by the pink color) seems to generate triangular shapes. Any idea where this is coming from and how to correct it?

Running version 9.13.8.22 on Windows. Both models are IFC 2x3.

Thanks for any insight.

Nevermind, found others with the same issue. Cannot delete the original post, sorry.
