Has anyone mastered the process of creating accurate extended rakes that are correctly depicted in Roof Plan & Elevation? I ask this because when we create a roof in Revit if we extend it beyond the gable wall  it's actual structural Depth is shown in Elevation, which in most cases is not what we want. The nicely detailed rake trim in most cases would not be a 2X10 rafter depth, if that happens to be the make-up of your roof. If we create a roof and do not extend it beyond the gable wall it still shows up in elevation with its structural depth appearing. Do we hold the roof back to outside face of stud then cut profile the wall and then sweep a rake profile along the slope. Doing that results in a portion of roof (in Plan) not being depicted. I am finding it very difficult to interface Rake (extended or not) with Soffit, Gutter & Fascia using Revit. I'm at this point assuming a lot of these issues have to be resolve in the 2d detailng?

Any pointers would be appreciated!

No 2D. You have a few ways to do this.

1. Model the roof as only the shingles and sheathing. I model the structure using actual 2x_ material so if the 2x10 don't go out side the gable wall I don't draw them. This way you can add the fascia or detail using a profile.

 

2. Model the roof as a full thickness. ( sounds like what you are doing ) Create an in-place family as a roof and select void extrusion. Draw an area to be removed from the roof. You can then add a fascia or detail again using a profile.

 

Good luck..

3RD WAY...

Create your main roof to the face ofwall and a second roor for the outlooks... then join geometry.  As long as your shingles are a layer.... Easier than the void.

WWHub - Have you developed any new and improved way to do this since 2010?

Not really, as you know by now, we are all constantly changing as our needs change so, now I might do an in-place void working in elevation and selecting the face end of the roof as my work plane... Not quite what Robin said.

 

And if you do this, remember extrusions from a workplane might have to be positive or a negative offset from the plane with a positive.  I can never remember what the rule is here for front/back & left/right so I do it and reverse it if needed.

The direction of the extrusion depends on the direction that the reference plane or grid was drawn from.  From the South, a grid drawn from right to left will extrude towards you, while a grid or ref plane drawn from left to right will extrude away from you.

Ah ... if only we could get our users to draw RP's in the same direction.   Even though I explained this many times, users often draw their column lines in different directions then have to individually change the bubble end in every plan view.  They are getting it but some just don't care.

 

PS.... The answer I gave above used the plane of the roof, not an added reference plane.
