Import Revit DXF or FBX into ConceptStation Model

Hello. So I've been testing the OpenRoads and OpenRail ConceptStation software for a little while now. Currently, I'm trying to import (through the furniture/component builder) a Revit Model into ConceptStation, but it gives me an error during import. I was wondering if there is a proper workflow between the two programs. It seems a 2D view was able to import without any issues, but when I tried with a 3D view, it gave me a "There was an error during import. Unable to continue." message. Any advice would be great!
