Hierarchical class structure of IFC4 (188.8.131.52). 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).
IFC4 Classification.xml - file for importing classification in Classification Manager.
IFC4-IFC4 Export Mapping.xml - file to set up export converter for 1:1 mapping of classification to IFC classes. Import the file in the Type Mapping presets within the IFC Translators.
