Multi-sloped Roof

Wanting to know the best way to tackle this roof. Can this be done using one roof?

 

Please see the original drawings for the roof:

The elevations keep getting flipped upside down regardless of any attempt to fix.

The main issue I am having is the different sloped roof over the front right of the house. However, this slope does not continue all the way across, so I'm not sure how roof by extrusion would create this. 

 

The roof above the front porch is about a 5.5/12, where as the main roof of the house which is also on the left side of the house is a 10/12.

I would extend the 8/12 and 5.5/12 roof over to the main roof. Then do join geometry so you get the outline. After that you edit the main roof profile and then you pick the edge where the lower roof meet.

I see an 8/12 as well.   

 

Post what you've got.  Also, do you have full Revit with Modify Sub-Elements Tools?

I'd use :

  • a Roof by Footprint with Cut Off made at the level of the lower Roof ridge height
  • and the second Roof by Footprint on Top of the first one with the same slope as the bigger slope of it..
  • Finally Join the two roofs..

no shape editing necessary.  

 

...but you can use alittle bit of everything one this one.   Defined Slopes, Roof by Extrusion, Slope Arrows.  Fun.

FWIW @BigPicture045 :

 

Shaped Edited using 3 Split Lines:

...if you have full Revit.

Of course.  One roof by defined slopes.  No roof by extrusion, no vertical cut, no extra roof, no shape editing.

For this project I am using Revit LT. I am unfamiliar with "shape editing" but from @barthbradley  post it seems that that is the tool for the job.

 

From what I can tell, the other answers used multiple roofs.  The main issue of combining the roofs is how they join together, especially on the right elevation.  I'm thinking I can modify how I use the fascia board to compensate for this.

Does it work with the 8/12s?

I would worry about that personally. But if you want it flush top and bottom, then use a thicker roof for the 5 1/2:12.  

 

...of a thinner roof for the 10:12.  Six of one; half dozen of another I suppose.

@barthbradley are you talking about the other side? I think this is one of those things I'm just going to have to do a lot of adjusting to get it right.

it looks like the solution can be more simplified ....without Cut Off....as can be seen in my screencast:

@ToanDN 

 

Something got lost in translation. The above roof examples that have been posted are not based on the reference images nor the original roof plan. On the left side, the roof does not extend past the front gabled roof. It actually recedes a few inches. 

 

@ToanDN When I try to modify the roof sketch, I get an error.

Yes, it still keeps the rain out with 8:12s.
