Cannot assign AirBoundaryConstruction to the wall face

I’ve not used AirBoundaryConstruction in rhino before so this is likely user error but:
Created two rooms, solved adjacencies, selected face, went to constructions and selected the Generic Air Boundary construction in the library, and received this message:

any insight would be appreciated.


Hi @tfedyna,

Try to change the Face Type to AirBoundary first before changing the construction.

Just to make sure you are aware of the other options you can choose the interior walls to be set to Air Boundaries when you run the solve adjacency command using the AirBoundaryOverride option.

There is also an option to set them by Guides.

Oh!! That makes sense! thank you! and thank you for the additional information!
