Cannot solve general adjacency and air walls

Hi everyone,

I am trying to learn and build a model with a simple house design. I cannot seem to get my walls to recognise when they are adjacent or if an air wall is present using HB_solveadjacencies.

Further is there a way for my ‘closed brep’ in the item selector to have a custom name for the zone so it is easier/faster to select (e.g. ‘bedroom 1’)? I have been looking through the forums and nothing I try seems to work and many of the older threads no longer have screenshots that load.
