I have a metal insulated roof at 3:12 pitch. Under the overhang there is a foam shape attached to the wall. This will not model correctly as a fascia, since the fascia attaches to the end of the roof, not the wall. So I tried to make it a wall sweep (component). On eves it looks fine, but on the gable ends it's cocked at an angle. What's happening and how can I fix it?

I would use an Adaptive Component with Orientation to follow "Global Z then Host XY"
Otherwise use separate Fascias/Sweeps for the eves and the gables then clean up the corners

I'm afraid I don't know how to create an adaptive component and I'm not sure how it applies to my specific need. I tried to create one but then could not extrude it along the path of the top of the wall at the eave and gable ends.
I did make separate sweeps per your suggestion but I don't see how to clean up the corners. Any further advice you can give me would help. This is what I have:

If you change the angle of a fascia it changes them all, not just the one on the gable end. Besides, I'm not creating this as a fascia, but rather a wall sweep.
Okay, so use separate Fascias and then Model In-Place the corner return. Pretty much how it will be constructed in the field. Probably going to require a custom pre-fab. That's where you come in with the plans.
Like this? I use a fascia, not a wall sweep.
Revit 2022 file (I don't have 2021).
I don't have Revit 2022. I tried to place the profile as a fascia, attached to the bottom edge of the roof, then moved it horizontally so it's under the eave. This worked on the gables but not the eaves, where the shape was tilted at the roof slope back into the wall. How did you get your fascia to do that????

- The fascia profile should not have a sloped top. The sloped top only happens at the eave sides, not the gable sides.
- Create another roof with a smaller footprint (matching the wall perimeter, no overhang) to host the fascia so that you don't have to move it. Hide that roof when done.
- if you care about the flat top fascia protruding in the roof above, create a void extrusion in place to shave off the top portion of the fascia on the eave sides.

Thank you, that seems to have worked. However, it seems to be a workaround. One would think this would be a pretty basic need in Revit modeling.
Also, I used the "cut profile" command on the view tab, graphics panel to modify the top of the profile at the eave.

Yes it is a workaround.
I forgot to mention that you can keep the 'ghost' roof in a previous phase and demolish it, or move it to a future phase, the fascia still remain independently from that roof. That would keep you from manually hiding the 'ghost' roof.
Also, Cut Profile is 2D only and per view but if it works for you then that is good.
Just make your Roof a Two-Cut Plumb and path the Fascia along the bottom edge of the Roof. Then enter a negative Horizontal Profile Offset value equal to your Overhang. Bada Bing.
It's not a workaround.
BTW: Don't slope the top of the Foam Board Profile. It's unnecessary and silly.

use a void to trim edges at the corner

I've tried all the other suggestions in this thread and yours is the simplest and least time-consuming. Despite the fact that it's a workaround and it requires creating an element that has to be hidden or demolished.
What I don't understand is why it is not easier to accomplish what seems to me to be a rather simple task. I can't be the only one trying to make this particular shape perform this way. Years ago, this kind of thing was simple using out-of-the-box AutoCAD with a sweep and a polyline. I have been using AutoCAD since 1988 and I don't understand why Revit has to be so complicated and so un-user-friendly.
Oh, well, I need a rendering and this is the only way to get it using the tools that cost a small fortune for a small operation. And going to all this trouble, I want working drawings out of it as well, no questions asked.
Yours,
Frustrated Fountainhead

If you want to create it as a continuous sweep, you would need a small horizontal segment to transition the horizontal eave to the sloped gable: a horizontal eave segment > turn corner > a short horizontal segment > a sloped gable segment.
Without the short transitioning segment, the sweep is likely to fail or distorted unless the profile is a simple circle.

I don't understand why you need a "workaround" when two-cut plumb accomplishes the same thing. Did you read and understand Message 16?
