Another 3D model in progress for a home I'm designing. This type of 3D cross section uses real framing measurements to build a 3D model of rafters, 2x6 walls, etc., to check the interior clearance for a second floor room with a contoured ceiling. Very powerful software indeed. I can pull out the measurements of any component, such as exact rafter dimensions, and put them on a final plan. Now, the carpenter won't have to think any more, just assemble.
