curved mansard roof

[ozren.stambuk679025]

Hi,

Can anyone walk me through the steps required to create a curved mansard roof as shown in the attached pic? I am not really sure how to begin doing this since I am new to Revit and I don't want to go down the wrong path. If you can set me on the right path even with a basic explanation, I will fill the blanks in my knowledge if I do not completely understand the answer. Any help is much appreciated.
Thanks a bunch,

Ozren

The Roof by Extrusion will allow you to create each side of the building's roof as individual sections of roof. You define a workplane (reference plane usually) and sketch the profile of the roof. Repeat for each side. The ends won't miter into each other so you'll have to use an Opening to "cut away" the excess roof.

Another approach is to use Model In-place > Roof and create a sweep that uses the top of the wall as the path and a profile, your roof shape. This will create the entire roof shape, less dormers and brackets. You can also provide additional sweeps, within the In-place roof for the each and parapet features. I'd probably take this route if it were mine to do (attached a mockup example).

Thank you very much Steve for that very clear answer. I am using 2014 and it will not allow me to open your file, is it possible for you to save it as 2014? Thanks a lot for your help in any case. This forum and the people on it are amazing!

No Save As to earlier versions, sorry. I just made it again using 2014 in the attached file. It took about 5 minutes...not hard just a few steps really. Harder to decide what size and proportions you need.

Hi Steve,

I managed to get it to work and it was very easy actually, once I looked into in place modeling that is. I have another question for you if you have the time. I am created a kind of dormer section at the front of the main mansard roof, and it also has to have a curved appearance. Is it possible to eliminate the extra portion in the main roof or somehow merge it with the main roof sweep?

Thanks,

Ozren

While editing the in-place family you can also create voids to carve away the parts of the roof solids you don't want. You also don't have to close the sketch of the smaller roof, form a "U" shape instead of a closed rectangle path. Extend the path of the smaller roof so that it goes all the way through the larger and use Join Geometry to get them to behave or appear as one, to generate the joint line between solids.

Ideally all the geometry and voids are part of the same in-place roof so they can interact with each other the best.

Be careful though to not make in-place families too comprehensive. Keep in mind, only one person can edit it at a time so if you start using worksharing and need other people to help you a single large roof, eaves, chimney, dormer, and other stuff in-place family might lock too much work up in a single user editing environment.
