Composite walls - Displaying core of Load Bearing elements

[Johan Stinckens]

For walls that seperate private units in an appartment building we commonly use a load bearing wall in which two structural skins are seperated by a layer of acoustic insulation -> concrete/masonry + insulation + concrete/masonry (see attached image).

Problem: ArchiCAD doesn't allow me to define two core skins either side of a finish/other skin.
Currently I have defined all the skins in the composite as Core elements. This however means that when I save a view showing "Core of load-bearing only", the insulation for these walls are also shown, which I do not want.

Does anyone know of a method to define a composite structure where the outher skins are defined as "Core" and the inner skin is defined as "Other"?

super secret trick: create a stretchable complex profile of the bits of wall + the air layer. You can freely define core/other/finish settings to whatever you please in complex profiles.

Hi Erwin,

Super Special Trick indeed!

Should have thought about that one myself.
But as it happens I hadn't ever used a stretchable profile yet, but I will surely do more now.

That said, I do hope Graphisoft will update composites so that core-skins can be defined either side of a finish/other skin coincidently.

Alternative is to draw two ' half' walls. I would not overlap the reference line though. There are some limitations with complex profiles and scheduling (can't remember what right now, but recall I had some issues), simply because complex profile can be any shape and composite by default pretty much is straight in all directions.
