Type definition

The IfcLibrarySelect enables selection of whether library information is to be contained within an IFC model or is to be referenced from an external source.

It is expected that selection will be IfcLibraryReference and only rarely IfcLibraryInformation. IfcLibraryInformation should only be selected in circumstances where there could be a need to indicate the libraries that will be used without making individual references. This may occur for higher level objects such as a IfcProject or IfcBuilding.
