Thanks for the info.
20 is a few years old so may not work 100% with the latest Mac OS versions.
Not being a Mac user I am not sure if 20 was designed for any of those you mention.
All I can say is Archicad 20 on a Windows system does show those layer icons.
Maybe someone else on a Mac can check?
When you place a drawing with the Drawing tool, there is an settings button to show "Drawings own layers".
