When exporting window styles with 3d geometry, which element do you attach the IFC data to, the extrusions the symbol or the window style. They all seem to come through in Solibri as solid black elements with the exception of some curtain walls which as frames and glass as they should.
We have several window styles using separate geometry symbols to achieve the window format not possible with the window tool. The IFC exports have not been successful, sometimes the frame shows sometimes not, they usually come through very dark grey. We don't if this is an export setting or if the IFC data is being attached at the wrong stage. Or is this an issue with using class styles to attach attributes.
Any help would be appreciated.
