The AIA CLG lists A-FLOR-CASE for case work. I have two questions here, specifically related to residential projects, both custom and production. 1: Do most people use this single layer, then force color/lineweight and linetype to show uppers differently? or do you use two layers, along the lines of A-FLOR-CASU and A-FLOR-CASL for uppers and lowers? Or do you not worry about keeping the layers together, and use something like A-FLOR-CASE and A-FLOR-UPRS? 2: The CLG also lists A-FLOR-WDWK for built in architectural woodwork. How many people actually use this seperate layer? If so, do you show built-ins graphically different, or identical but you have a different layer because you have plans that show one but not the other? I am working on a residential specific adaptation of the CLG for my consulting clients, and I am curious what others have done in this area. Thanks, Gordon
