The bad thing about extruded roofs is the fact you can t follow along with the footprint of your building the good thing is we can do something about that the objective of this video is to go to the plan view we will then create a void where our walls jag in and out this is going to allow revit to cut the roof properly in plan to get started jump into your revit roofs.
Revit trim intersecting roofs.
Use it to extend the dormer roof to the main roof.
Then you can trim the roof faces to this line.

This tool is located in the modify tab.
You can join roofs to other roofs or walls or unjoin them if they were previously joined.
Select the slab or roof slab to be trimmed.
