Cavity visibility misbehaving in plan

[danielathay]

I've assigned a Cavity material, with an intersection priority of 950, to a slab and positioned it in front of my windows. I'm doing this to cut through an additional layer of independently modeled siding. The cavity successfully provides the desired reveal in both 3D and section, however, the siding is shown running continuously through my plan. I would like the cavity to function the same across all views. Can you offer suggestions?

At what height is the floor plan cut plane and what is the floor plan display of the siding?

And how did you model the siding - objects, complex profile columns, wall accessory?

A wall accessory is the best option as it will cut the windows automatically.

Here is one created by @Hmooslechner that I modified to English and have tweaked a couple of settings.

I just uploaded the lates version i have.

Does the siding have a Projected representation? Symbolic will not display the BM intersection of building elements other than wall to wall.

Barry,

The floor plan cut plane is set to the default, 4'-0", and the display is set to Projected with overhead.

The siding is modeled as a complex profile column.

It might be like a Solid Element Operation.

The slab has successfully cut the columns in 3D, but the result does not show in plan.

I don't have Archicad running at the moment to check.

Are your windows sills below the 4' cut plane?

You could also try to solve this whole situation with the Curtain Wall tool. Looking at the 3D of the siding, the hole and the frame around the Windows, I think all those could be modeled with a single Curtain Wall element. Plus, that could give you a proper floor plan representation based on the Floor Plan Cut Plane height.
