i want to analyse stadium daylighting performance. i designed the stadium using RevitArchitecture program. But it's roof designed using Rhino program(dwg format) because it's very atypical. Then roof file imported into revit program, add up stadium file. i exported this file gbXML format and i tried to import VE program. But roof shape is not indicated on VE. Only stadium shape is indicated on VE. What is the reason? I wonder if VE recognize file only designed using revit? Please help me.
