Hi,
I have a model where I put openings in the walls. This are just standard Revit openings, both doors and windows. Inside a family there is only stock opening. I export it to IFC file and then when I open it in any IFC viewer some of this openings have opening volume in it and some do not. Any ideas what is the cause of sucha bechaviour?
