In order to create the roof and define its slope, you need to select the outside face of the exterior walls. So the flat roof extends to this outside face of the wall. What this creates in elevations and the 3D drawing is a line showing the thickness of the flat roof. We don't want to see this roof thickness rendered. And we also have conditions where the exterior walls are taller than the roof itself. How do you render the walls as being taller (parapet conditions) with a roof that has a minimal slope?
Thanks!
1. No, no, you don't need to select exterior faces of walls in order to create a roof. Not at all. You can create a roof without any other elements existing in the model at all. You pick a LEVEL to associate the roof with (which is done by default if you draw the roof in a floor plan view, because the floor plan view is associated with a level already) and then you sketch it's footprint. Now you CAN sketch it by selecting walls, but you can also use any of the drawing tools available. So you can define the edge of the roof along exterior wall face, along interior wall faces, or wherever you want.
2. Walls have a couple of important parameters call Top Constraint and Top Offset. The Top Constraint usually defaults to the next higher Level, and the Top Offset defaults to 0'-0". If you have walls up to Level 2, and you built your roof on Level 2 also, then give the walls a value in the Top Offset parameter to raise the tops of them up higher then the edge of the roof.
3. If your Revit guy doesn't understand these very basic concepts yet, send him to a beginner class, or at least have him spend thirty minutes watching youtube videos.
