multi pitched roof

[t1.shep]

I'm having a hard time creating this roof in Revit. The image attached is from sketchup, and I know I could import that and make a roof from the faces, but I want to be able to do this in Revit.
Any ideas?
It's basically a gable roof with a sloped ridge. I've tried defining opposite eaves as slope defining and then using a slop arrow at the ridge, but can't seem to get it to work. The slope arrow doesn't slope the whole roof.

Hi t1,

Although there may be better ways, I would probably model the roof with roof by extrusion.

Set two reference planes, one for each side of the gable roof. Create the roof by extrusion on those planes, then join geometry / join roofs to attach one to the other and then to the main roof.

Hope this helps,

Cheers,

Ian

That is the only thing that comes to my mind. Just do the "roof by extrusion"

In addition to roof by extrusion you might be able to set up a reference plane in the incline you need and then set that as your workplane. Then do a roof by footprint.

I've tried these tips, but can't seem to get it to work. I could be doing it wrong. Here are some other views.
If someone wants to make a quick example that I could look at that'd be great.

I tried my suggestion and it would not work. I could not select the inclined refernce plane for my roof workplane. :-(

I was able to do this massing the shape first and then doing a roof by face, but you wanted to do it another way. Seems like "by face" was not all that hard to do. Why not just use that option?

Can you build it as an in-place family, but categorize it as a roof?

[dhurtubise]

InPlace will work for that

A slope arrow corner to corner from lowest to highest will work as well, if you have a reference by which to determine the slope or the height change...

EDIT: Whoops, didnt see the other piece of it. I suppose you still could with two slope arrows, but its a pain in the rear...

EDIT2: wasnt a pain in the rear... That was just indigestions. woooo

I gave it a whirl.

Slope arrows work fine, the roof just gets a bit rude when you want to join it to the main roof, if you try using the Roof Join tool. But i suspect youll have that issue either way, whether you go with In-place (can you USE roof join?), or massing (youll have to manually trim the mass regardless...). So its six of one half dozen of the other...

Yeah, youll have to sit there and figure out the math/geometry first, but i dont see a way around that regardless. Welcome to architecture, haha....

EDIT: In Cantroof2 i exaggerated it a bit more, to make it look more like the OP's photo. Sorry its not exact, im operating by buttdyno here, lol...

EDIT2: Also worth mentioning: Which function is DRIVING the shape and slope of that roof? IE, the amount protruding off the front, is it definitively at 90" to the angled soffits running back and up the sides? Whats *driving* the shape of it may very well determine which one of these methods will work best for you.

If you dont get it figured out today, shoot me an email and ill give you an FTP site you can upload the model too. I'll ammend the roof i made generically to fit the appropriate size of your project, and ill stick it on there and send it back to you... Email is below. :)

a method you might like to try....

a. Mark out your roof with reference planes.
i. plan area (both eave and ridge).
ii. slope in elevation (both eave and ridge).
iii. create a perpend from the end of your eave slope plane to you ridge slope plane.

b. Create a roof by footprint, and draw your outline....

c. finish the sketch and select the roof.

d. in the shape editing tool on the ribbon, add a point to the ridge at the top end.

e. Adjust the heights of 2 ridge points to be above '0'

f. in elevation, select each point, then use the drag control till it snaps to your reference plane. Remember to select 'modify sub-elements' if you lose focus.

g. create an in-place family.
i. Create a void sweep
ii. select the 2 top barge lines, and extend them past the end of the roof.
iii. in elevation modify the sweep profile, making sure that the inner edge is parallel to the top barge line.
iv. finish the sweep.
v. use the modify>cut tool to cut the roof with the void.
vi. finish the family.

Voila.
