Ship's Prow / Sloped Ridge Roof?

[Base12]

I can make this roof in Sketchup, and I know I can bring that into Revit and do a "Roof by face"... but does anyone know how to make this roof in Revit?  I know I can clip the corners off by using a vertical opening, but how to slope the ridge line with it still being a gable?  Raising one eave of the gable end didn't work.

Roof by Mass Face is one approach.  

Got full Revit? Another would be to Shape edit a flat Roof with Modify Sub-Elements Tool.

you can use a Roof by Footprint with Slope Arrows

Here's an exaggerated example of your "Ship's Prow" using Roof and Modify Sub-Elements:

This is great!  I didn't know you could use multiple slope arrows on the same roof plane to control the slopes like that!  Brilliant!

I didn't know you could do that either.  Still, how would control the slope and pitch?  Seems difficult and impossible.  I can play around with slope arrow's slope to get the front-to-rear slope near dead-on-ballz accurate, but I can't find a way to change the pitch from eave to ridge with this method.    

School me @constantin.stroescu.

I see that per Constantin's screen cast that the closer you move the tails of the slope arrows toward the end of the roof they are pointing to, the steeper <edit, they approach> the designated side-to-side pitch... however, as you note it's a bit soft on exact slope.  I know it may not be best practice, but for now I got it eyeball close and rounded off the units of the slope arrows and it gets it done.  I would like to know a more exact method for this because otherwise it's really easy and avoids the nightmare of getting walls to attach to roof-by-face objects.

[barthbradley]

Your discovery is my discovery. There doesn't seem to be any control using this method. It's cool though.  

I would just use Modify Sub-Elements myself.

With Modify Sub-Elements you can be dead-on-ballz exact.

@barthbradley

Indeed, modify sub-elements does a much more precise job of it!

[constantin.stroescu]

as a comparation you can see how can the same thing be done using Roof by Footprint with Slopes cut by Voids.

and the geometric explanation:

with Voids - the same result>>
