Hierarchical class structure of IFC4 (4.0.2.1). Class extents have been modified to provide a 1:1 mapping for Archicad IFC export. Classes with full names in parentheses are not recommended because they do not allow mapping to a class in the IFC converter settings (the mapping is set to the parent class).
