Creating a Gable Roof

[20079741]

Hey, needing helping with a gable roof. If you look at the images here you will that the roof type is a mix of a gable and hip roof. The problem I'm having is creating the roof shape in plan as the roof ridge of block 1 is not in line with roof ridge of block 2 as block 2 has a bigger width. As a result Revit only picks up the ridge line of the primary block and extends that over to the other end (block 2) with out picking up the midpoint/ center line of block 2 if that makes sense?

So what you end up getting is block 2 will look like this in elevation (look at the south elevation image), which is a problem. How do I fix this issue and create the roof shape i want in plan?

Draw the main Roof as a single item ignoring the 2 offset gable elements

Draw the 2 Gables as separate roofs

and once you place with the main roof slopes etc. use Join to Roof Tool on the Modify Tab > Geometry Tab

Not sure why you couldn't use one roof? 

Are you trying to exactly replicate the ridges and valleys you see in an askew, shaded satellite view of an as-built?  That's going to be near impossible. 

FWIW, I'm seeing Roof Offsets. I could be wrong.

So i've used other information build my house model as well, not just that image and I managed to have the model close to completion. Issue I was having was the ridge line for both block 1 and block 2 lets say. If you look at the roof image, the ridge line isnt continuous all the way through and offsets once it hits the midway and then continues on again. The one roof method only allowed me to have one straight ridge line instead from block 1 to block 2. If you look at the 2nd image of ground floor you'll probably get where I'm coming from.

The blue lines on ground floor plan represent where the ridge lines should be

like this? If so, a different pitch on that gable side moved ridge. 

Still, I'm not understanding why you are taking cues from a satellite image when you have the actual bearing walls modeled.

I would keep the opposing pitches the same by building/modeling it this way. Maybe this is what's happening in that satellite imagery.  Hard to tell exactly.    I doubt that gable is constructed with different pitches though.

No the image was just used to illustrate the roof shape I was going for, sorry if I didn't make that clear

There are pitch differences if you look at this image

Looks like both sides of both gable roofs have the same pitch to me.  But whatever floats your boat. You're the designer.  Point is that you can model all the roofs together with one roof - or with multiple joined roofs.
