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)
Thanks! This solves part of the problem 
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
Can you please share the method you followed to export from revit? Thanks
Hi ae,
Would you mind sharing the best practices you found to export from Revit and perform a complete energy analysis?
FYI, the best recommendation that I can give for this now is to use the Pollination Revit plugin while it is still in free beta for the next month or so:
As you can see from the images there, the tools in the Pollination Revit plugin are a lot better than Revit’s native gbXML exporter at helping get clean analytical models out of Revit.
