Walls: support for separating cavity walls, two structural cores

[Christiaan]

We need support for separating cavity walls, which have two structural cores.

Tick this one up as one I would have expected to see in there from the start.

How do Revit/Archicad deal with this?

What do people think is less onerous?

1. Model separating party cavity walls with two walls, so I can auto-bind the slabs to them properly and join wall cores properly? But then have to manage two walls and can't insert doors without having to create a separate opening in the other wall.

2. Model them as one wall, so I can insert doors without needing to create a separate opening in the other wall? But then have to manually manage slabs.

As a workaround:

Could you define & use a wall-style that treats both cores & cavity as a single component and replace it with the correct wall-style later in the project.

I understand this doesn't resolve the problem nor negate the reasonableness of the request but may help in the meantime.

Not sure how this would help Brian?

Your slabs could be bounded and doors easily placed.

Thicknesses & positions would be correct,

Component joins would need to be done once the wall is replaced.

Slab would not always be bounded correctly. Some slabs need to go to through one core and not the other. The slab will only be correct when it doesn't need to go through it.

I tried the two, and I can tell you that VW doesn't handle two walls very well, especially with wall joins. It really flips on them.

I know find it easier to draw the walls as one, and clip the slabs. I know it's some work to clip the slabs, but it's easier than redoing all wall joins over and over again and finding your slabs unbounded every time.

Great, thanks, I was dreading the two-wall idea!

Yes please, between this, and trying to work around several stepped slabs is driving me mad. Also component offsets in walls need to be independent of the wall style, this will give greater flexibility without having to unstyle the wall.

How about adding Fit Component to Roof/Geometry while we're at it......
