Revit Tutorial - Understanding Your Roof Eaves / Soffits




In my experience, the roof tool is still a mystery to many Revit users. Either they have only had to create flat roofs, they have been using extrusions, or they just haven't been using it correctly.  If you are one of these people, it's okay... You are not alone!

For the reasons mentioned above, roof tutorials are always the most searched on this blog.  I was demonstrating an eave detail to a colleague of mine when it was apparent that he had NO IDEA you could do what I was doing... That led me to this post.  A simple run down of the different eave (or soffit ) settings effect your roofs...

The following is a section view of a gabled roof with a 6"/12" slope.  By selected different "Rafter Cut" settings and "Fascia Depths" I am able to create a multitude of different details....

hi jeff,
my first time posting here,

another mystery about the roof, does the overall thickness represents the outer material+underlay (insulation)+supporting frame+main structure. i know its all depends on lod. but in a general workflow/ conceptual would it be enough to use the overall thickness to represent the roof?
Thank you! I have not looked at the fascia depth parameter but that is exactly what I need.

Since you had soffits in the title I thought I'd chime in on that. I typically draw a ceiling due to fact that I need lighting to be hosted. The soffit option does not seem to do the job. Is this a good practice or is there a workaround for that?
