I need to build a gambrel roof in Revit. One solution I can up with was to create two roof section that mimic one side of the roof, and then mirror those at the ridge point to create the other side. Unfortunately the two roof section to form one side appear different, and the whole thing looks a little odd when completed. Has anyone created gambrel roofs in the application, and if so can you share your wisdom with me. I’m using version 6.1 before you ask!
Thanks,
Alan

You could try one of two options:
1. Use the Roof by Extrusion tool to create the roof, sketching the gambrel shape that you want. Note that the resulting roof may extend further below the eave than you intended based on your sketch.
2. Use Create-in-Place roof, and sketch an extrusion that mimics the gambrel shape

Hi,
I figured out how to use the Roof Extrusion Tool last week, and got the results I needed.
Thanks....

While I realize that this reply is a few years old, I hope that it can be of use to anyone scanning through the forums with current problems. I spent about a half hour playing with the Roof -> Footprint command to make a Gambrel roof and finally figured out how to get it to work. I prefer roof by footprint because of it's association with a level, and the easy of future manipulation. Create your Roof sketch as usual (mine was a simple rectangle) and draw 4 slope arrows along one edge of your roof. These should be in the direction of the slope. I recommend the use of reference planes to divide your roof into quarters, including a center point (ridge), and a reference plane at each point of slope change. Making sure the reference planes at points of slope change are equal is crucial to the roof construction. Set the slope for each slope arrow according to the desired roof shape. Lastly, and most importantly, select the two slope arrows leading to the ridge and set a height offset at tail which corresponds to the height of slope change in the roof. It sounds more complicated than it really is. I hope this method meets the needs of whoever may read this.

Old post, but that is a good tip there. I usually do the extrusion method, but I will try that out.

You are overly complicating this, roof extrusion is so easy.
