Problem with GBXML import - missing floor and windows

Hi,
I am trying to import via HB a simple GBXML created by REVIT.
What is interesting when loaded into GBXML viewer Spider everything works:

But in GH I have no floor (the brep is there, but HB does not read it as floor) and the windows do not cut walls.

[gbxml-test.xml|attachment]

I am attaching the sample gbxml and gh file

gbxmltest.gh (20.4 KB)

gbxml-test.xml (629.8 KB)

Hi/Cześć @ae Mateusz :slight_smile:

Slab on grade is defined as groundFloors in Honeybee.

Thanks! This solves part of the problem :slight_smile:
I see that also on your computer windows are still not cut.

Hi @ae, that is most likely a visualization problem. In EP there is no cut in the parent face. We subtract the child surface from the parent surface just for the visualization purpose.

Thank You for Your answer! This is good to know this is only visualization problem.
Anyway I have found the problem: the reason was the wrong method of exporting GBXML from Revit. Now everything works properly even with automated frame thickness and roof shading

I think I have a working proper method now 100%. When I will test it I will make a post I think
