composite wall: interrupting wall finish after certain height

[HelenE]

Hello everyone!

I need some help in modelling some composite walls. As you can see from the attached picture, I would like for the tiles of this composite wall to stop at the level of the suspended ceiling but I need the wall's core to continue until the concrete slab. Is there a way I can model this so that when I prepare the schedules to calculate the area of tiles required the total will be correct? Is there a way to this quickly (without creating a complex profile because we would have to redo many walls that are already modelled)?

I just wanted to thank everyone for answering my question. We will most probably go with the 'plenum' building material idea. I appreciate everyone's contribution!

Glad you find the best solution for this case.

I also like the idea of plenum BM, thanks to all.
