I’m producing IFC’s from the arch model to the MEP consultant
in our project. The model is rotated 30 degrees and when MEP
opens the IFC in Revit, Revit can’t find the room boundaires.
We did a test where I just exported exactly the same model
without rotation and Revit could now find the boundaries.
My question is what triggers this behaviour? The IFC-model is
top notch and the project is in fact rotated (it’s a part of a
bigger building that has quite odd geometry).
