Cavity wall as composite or seperate walls?

I'm curious after your opinion whether you should draw a cavity wall as composite or separate walls in ArchiCad.

Hi, Archcad gives you the possibility to create custom composites and there is no benefit to do cavity walls by drawing separate walls for inner and outer surfaces. It will save you lots of time and energy!

I understand using composites might be confusing at first but with practice, it will become part of your workflow.

One issue you might have when drawing a cavity wall with composites is at the intersections where walls won't interrsect correctly, in that case, you need to adjust Priorities in Building Material menu.

Set up same value for inner and outer skin and higher value for cavity (for cavity you can use Air Space)

Composites definitely - so the skins are all one wall.

Separate walls for each skin will be a pain.
You will have to adjust each one and cut empty openings for doors and windows as they can only belong to one all so won't cut holes in the other skins.

Also complex profile walls are great (especially in 22 with the profile modifiers) as you can have walls with corbels, separate heights to each leaf, footings, etc.
What you can do is almost limitless now.

This image is the same wall profile, but the modifiers have been stretched in each instance to provide different walls.
All the blue lines are stretchy - I could have added more.
