No visualization with HBColorZones

Hi all,
I´m simulating a single room (only 1 thermal zone) with E+ but I can´t visualize the zones with HB ColorZones. It never happened before though this is the first time I have 1 zone.Thanks in advance. hospital_room.gh (861.7 KB)

It’s working fine for me after I took out some non-ASCII characters in your zone name.

Great! Thank you for your soon response! But if the room only has 2 external walls and the rest are adiabatic, why not decompose the brep and join the surfaces with their boundary conditions?
