What the heck!! Revit's "special" roofs.

[snurresprett9]

When I create a roof in revit, the portion outside the walls (overhangs) are the same thickness as the rest of the roof!! Also the insulation continues on the outer side of the walls. That's just crazy! Cant seem to control this in any way, must be some kind of bug...

No bug, do a search, there are several ways to accomplish.

Hmm... only way is to make two separate roofs I guess. Clumsy workaround!

[dbaldacchino]

Or an in-place void of the roof category to cut the unwanted thicknesses?

[mmodernc]

Need same control as for walls i.e. being able to split roof layers so conditions from eve to wall (fixed distance) can be different from rest of roof.
Any sign of Revit 10?

This may not be the place to post this, but I would like to see something about roofs on the wish list.

Although I think the roof tool gets the job done, and it is quite intuitive, I mean, it does build roofs!, so there's not to much to complain about. But on the subject of future improvement, I would like to see the roof tool become more interactive. I think defining the overhang condition would be very helpful. The ability to basically define multiple roof conditions within the same roof, as this is something that is quite common from roof to roof.

I would like to see heights, offsets etc. more controllable within the same roof, instead of having do do several roofs that make up one roof. I would like the roof to be able to relate to the walls in more ways than just knowing if it's boundary was defined by a wall. It would be nice to have the roof read the wall height and be able to give you options to allow for these different heights.

I think the roof tool becomes quite cumbersome when you start in on a complex residential roof. Some commercial as well. I wouldn't really mind building multiple roofs to get it done except the roof join tool is so finicky that it makes it a real challenge. Like I said, you can still get it done but it would be nice to have an easy, interactive roof tool in the future. This would save time for all of us.

With regard to roof overhangs, I'm beginning to think the way to go in some instances is to make multiple roofs that are stacked on top of each other. I'm building a roof now with one "roof" that represents the sheathing and standing seam, and another roof below it to represent the depth of framing within the outside wall boundaries, and then of course there's the ceiling. The soffit volume is another object.
I currently have two residential projects on my desk, and I am finding that in transitioning from schematic/dd to construction documents, the drive to have the model provide a good depiction of the actual wall/floor/roof asemblies has caused me to rebuild the model using smaller parts, like for the roof.

[ford347]

I generally find myself modelling the sheathing and actually creating the structural elements for the framing, especially in the floor structure, since structural framing in flat conditions works quite well. The roofs are a little different story. I generally burn a lot of time in the structural framing in the roof.

Both our floors and roofs are now just the actual floor/roof. All structure etc is handled via detail componant or model and batt insulation is at the detail level. Our rigid insulation is embeded in the roof strucure and we use a second roof for uninsulated areas
