I am having problems exporting revit file to gbXML file. I am using Revit 2013.
As shown in the attached picture, the roof of the model turns out to contain a shading part, which is not exist in the Revit model. And during the process of exporting it, the entire roof is completely in the exported data. But when I view it in google sketch, shading appears on the roof.
I have also attached the original Revit model, could you help me check with it and what I could do to fix this so as to make the model maintain the original geometry?
Ps: sorry the model exceeds the maximum size of the attachment. ......What could I do...
