Building Materials are attributes, defined at Options > Element Attributes > Building Materials.
All Archicad model elements use Building Materials in their structures. Building Materials are also available for Stairs, Railings, profile elements, and certain Library Parts (in the INT Library: those in the Building Structures Folder and RoofMaker Library Folder).
Building Materials are also used as components of composite structures and profiles.
Each Building Material combines the following:
•Cut fill
•Cut fill pens (foreground/background)
•Intersection Priority
•Fill orientation (relevant for a composite or complex element)
•Surface
•Classifications and Properties, including Physical Properties
