Working with Slab Shape Floors in Revit can be a tedious process. There are two options for creating sloping Floors: use a Slope Arrow for a single slope across the entire Floor or convert the Floor to a Slab Shape and modify its points and edges. Unfortunately, there is no way to combine these two methods in the Revit UI.
Ideally, you would be able to start with a Floor, give it a single slope, and then convert it into a Slab Shape. But of course, this is possible with the Revit API and can even be done with Dynamo.
