Dormer in Roof

[Anonymous]

Hi all, which is the easiest way to create a dormer in a roof?

Thanks

Have you checked THIS article from the Autodesk knwoledge website?

With a second roof just for the dormer, joined to the main roof. It's also useful to place an opening through the main roof for walls to go down through, if it's actually a usable dormer space accessible to people as opposed to just being an ornamental one sitting completely on top of the main roof.

It depends on what type of dormer you want to build (Gabled, Hipped, Shed, Segmental, Eyebrow...).

1. It could be a very simple gable-end basic dormer which you can create simply by editing the roof's foot print and adding two slopes arrows eave.
2. Most Gabled, Hipped and Segmental dormers are easiest with Roof by Extrussion OR Roof by Footprint tool (similar to the example described in the link @L.Maas gave THIS HERE
3. Some Segmental and eyebrow Dormers are better done when Modeled in Place using Solid Blend
4. It could also be a bit more sofisticated eyebrow one where its better if you use conceptual massing and play with ref points therein (it can be done in Revit and sometimes it would be more convinient to use something like Dynamo or GH). Here are two examples one by Dzan and another by Constantin for the same  type (I will call it Dutch or Deutch) Dormer as there are pretty much common here. https://forums.autodesk.com/t5/revit-architecture/cone-roofing/m-p/6028938#M108601  

Besides that; there seems to always be more than TWO ways to do ONE thing using Revit. All (as long as its kept within Revit) are easy and just depend on one's own preference or how one is used to work.
