I m used to showing tapered sections that slope 90 degrees to the main roof slope almost like a very flat hipped roof with ridges perpendicular to the roof and valleys making 45 angles if the tapered is the same slope as the main roof or around 22 5 if the tapered is half or twice the main roof slope.

																	For clarity sketches for 2 separate ceiling elements are shown together in the illustration. 
																	In the option bar make sure defines slope is activated for boundary lines. 
																	A variable thickness material used to slope the surface of a horizontal plane for example tapered insulation. 
																	In revit a ceiling element can slope in one direction only.

																	Technonicol plugin is a revit program add in that contains tools designed to create slopes on a flat roof using tapered insulation sandwich construction leaders as well as catalogs of building systems materials and sketch books of connections.
