How to Create a Mansard roof

The roof tool in Revit is a very simple tool to use but you can get some very complex and interesting roof designs from it. In this tips & tricks we are going to cover how to create a Mansard Roof

You may not have noticed this before, but Revit has the ability to “Cut” a roof at a pre-set height. This is extremely useful if you are trying to create a roof shape similar to that in the image to the Right:

This process consists of three simple steps; 
follow these steps to get a similar output:

 Step 1: In your project, go to an elevation view, and add in a Level at the desired “Cut off level”, as shown in the image

Step 2: Go to your Eaves level floor plan view and sketch in you lower part of your roofs footprint and put in the desired slope. Before you confirm the sketch, in the Properties, click the drop down list for “Cut off level” and choose the level you just placed in the elevation. This will cut the roof at that pre-set level height.

Step 3: Go to the floor plan view for the cut off level you created and sketch the footprint of the top section of the Mansard roof & set the slope, using the lower section as a guide. Once done, you will need to switch to an elevation  view and move/Align the two roofs so you have a seamless slope change

And there you have it, three very simple steps to creating a Multi Pitched/Mansard Roof. This process can be used to do as many changes in pitch/slope as you want, it will just take a bit more time to do.
We hope you found this tips & trick article helpful
