How To Join Roofs On Different Elvels In Revit

There are settings in revit to make roof edges at different heights but thats a real mess to set up right.

How to join roofs on different elvels in revit.

Located in the architecture tab this tool is used to create a dormer shaped hole in the main roof. To let the jacks sit plumb on top of the sleepers we angled the level cuts to the 3 1 2 in 12 pitch of the shed roof setting the circular saw to a 16 degree bevel the degree equivalent of a 3 1 2 in 12 pitch. I have tried creating 2 roofs and joining them but have had trouble with this as well. Create a dormer opening.

Click modify tab geometry panel join unjoin roof. Click edit footprint to enter the sketch mode. Select an edge of the roof that you want to join and then select the wall or roof to which you want to join the roof. Use it to extend the dormer roof to the main roof.

Then from the modify tab on your ribbon use the join geometry command and select the 7 1 2 roof and the wall. If you see the symbol then the edge will be generated having slope.

Select the wall and use the attach top base button to attach it to the underside of only the 5 1 2 roof.

The value can be different for each edge. I have uploaded a picture of the cad elevation i was given to produce a 3d and my current revit elevation. And then join them together using the join unjoin roof tool in the modify tab. It will join in the wrong order and you will need to use the drop down menu next to join to switch the join order.

Select the main roof then click on dormer walls and roof. To do this method you need to select the roof and edit the roof footprint. To make the bottom cut i laid out a level cut for a 4 in 12 pitch. I think the easiest way to do this is by modelling 2 seperate roofs.

First model the 2 roofs. Use join unjoin roof tool. Select the edge and change the slope value. Basically the roof is not looking like it should and i do not know what is happening.
