Just thinking out there. Is there a way to export just the outer face of the building and roof. Basically just the outside of the building (nothing inside) to a 3D Model? I was curious if I could do that, then import that into a dwg. Xref that into a design file (Grading Utility) just to see if everything lines up. (Roof Drains, steps, cleanouts) stuff like that. Again just a thought.
