hi ,I am a primary user of dialux, I describe u so long time, I never comment , but right now i met a issue for consulting you. When I use Revit build a 3d modeling and output IFC file, I use other 3d application (BIMvision, sketch up), did not show me any problem about IFC file, but dialux when I input in dialux, it can show the wall information to me, turn a word, it did not input wall information.
Following your video, your iIFC information just include curtain wall, the wall is not standard wall, i will follow your video to get a result about my issue.
