OBOS Appendix A - IfcElementType and PredefinedType enumerator listing

Appendix A - IfcElementType and PredefinedType enumerator listing.

This appendix to the OBOS provides a list of the IfcElementType’s, and their associated PredefinedType list of enumerators, from the IFC4 (ADD 2) schema. The list below can be used to designate the BIM object in IFC, in accordance with clause 3.1.1 and clause 4.3.2 of the OBOS. The IfcElementType’s are listed in bold formatted text below, immediately followed by the available PredefinedType enumerators for that IfcElementType in CAPITAL letters.

The IfcElementType shall be used as the value for the ‘IfcExportAs’ property and the PredefinedType shall be used for the ‘IfcExportType’ property. For the example of a Steam Boiler, the value for the ‘IfcExportAs’ property would be ‘IfcBoiler’ and the value for the ‘IfcExportType’ property would be ‘STEAM’.
