Revit 2015 R14. I have an Architectural Column i'm using as a pilaster. It's 4" deep off the face of the building. We're switchign from a 6" metal stud to a 6" + 4" metal stud at these locations. The problem im having is the wrap doesnt look as expected. on the left, is what im getting, on the right is what i expect.
It seems to only wrap the projected distance out and uses that distance to wrap (in this case - 4 inches).
Am I doing somethign wrong here?

Why not just use what's showing on the right then ?
Are you trying to use the vertically oriented wall as one continuous wall and have it automatically form around the column ?
I'd be interested in where the core of the wall is as well.

The left and the right examples are exactly the same walls and architectural columns. The difference is the architectural column on the left is poking out only 4". The one on the right is poking out 7". I see i made an error in my initial graphic, I should have dimensioned the wall bump out as 7" as opposed to the distance from the face of stud to face of brick.
I can't use the one on the right because we only want the pilaster to be 4" deep.
The wall is as assembled in the attached image.
I am still stumped by this behavior. At this point i will have to correct it in the details and let the floor plans display it incorrectly unless someone can think of something I’m either doing wrong or a change I should make.
The wall is the metal stud, which is 7" back from face of brick. If i move the dens glass and insulation back into the core the "wrap" on the architectural column works.... kind of. It doesn’t wrap those objects - only the brick. The airspace ends up growing.
What we are going to end up detailing is switching from 6" metal studs to 10" metal studs at these locations. And the dens glass, insulation, and weatherproofing will all wrap around it.

I had never liked the way this worked so I don't use pilasters for column wrapping. But I was curious as to what is happening and here is what I see.
- If you start with the pilaster face 3 5/8" off the wall face (the thickness of the brick layer), the brick is just 3 5/8" thicker.
- Bump it out to something more like 3 3/4" and only the brick layer wraps but the air doesn't really wrap.
- Move to 5" and the brick and air is wrapped.
- At 5 1/16", the insulation turns out but doesn't wrap
- At 5 1/4", you get thin insulation wich thickens all the way to 6 1/2"
- Keep going and you start to see the Dens Glass
CONCLUSION: The only wrapping layers are those that will be outside the exterior wall face line.

Your findings match what I had been seeing. Very strange behavior.
Do you recommend a different approach? I tried using walls to turn the corners, but I have a few particular situations where the pilasters works alot better than wall returns. I have corners of buildings (easily done) and some that sit 4" off a face of balcony (see attached images).

I don't think its a strange behavior - just how Revit is built and maybe it should change but I don't see offhand how they could re-write it.
In cases like this, I have used thin walls that are grouped for ease of placement. But those return walls can be a problem because they will be short. That group needs a void to cut the layers of the main wall... not an easy build.

Probably the best workaround for this is to have two seperate walls. One for the core studs and one for everything else. Model the core in a straight line and then have the brick and insulation and whaterver else in the other wall and model it in front of the core wall and then have it bump out for your pilasters. This should fix the wrapping problem as the core would be completely seperate from the the walls that are wrapping.

I understand the concept. I'll give this a try.
Thank you.

what a pain. but. it did work. I made it a group - It took me nearly 45 minutes to get the corner bulding cleanups the way I wanted them in the group so they would stick on all floors.
On to the side pilasters now.
Thanks!

I did. It was certainly not an easy solution, and perhaps it could have been simplified... but.... I managed to make it work with 3 main groups, and I have a few odd groups at other levels due to differences in the plan.
