IFC Classification Reference

A Classification Reference (IfcClassificationReference) is used for arrangement of IFC elements into a category. You can assign an Item Reference identifier, a classification Name attribute and some other optional parameters to all project elements (such as the building, the stories, the building elements, or the zones). For example, classify building elements by the proper OmniClass table required by the US GSA, or by the Uniclass classification system required in the UK.

You can classify elements with this system both in IFC Manager and the element Settings dialogs.
