Appartarment create with Aec Extended Wall in Propotional Unit setup for Radiosity.
The model include parametric door and windows, you can move the position of Door and windows without Boolean operation, because a parametric object already Perforate the wall Alone.
The object have architectural material assign for the best render and Mapping coordinate., you can change the material easily and quickly because this material assign automatic coordinate to the object how doors and windows.
The radiosity are already calculate in 3d max 7.5 Ilumination with day light IES SUN
This appartament are design from an existing plant.
