IFCQuantitySetDefinitionCreator

Creates a feature whose attributes contain the definition of an IFC quantity set. The features output from this transformer are similar to the QuantitySetDefinition features produced by the IFC reader. These features define the names and types of quantities in a quantity set. The features output from this transformer are intended to be routed to the QuantitySetDefinition feature type of an IFC writer.

When writing an IfcQuantitySet or IfcElementQuantity object, the IFC writer will look for a quantity set definition whose name matches the name of the quantity set object. If a match is found, the writer will write out the quantities listed in the definition, taking the values from the quantity set object itself. In this way, quantity set definitions provide the schema for quantity set objects.

This is done because FME feature attributes are not able to define their data types in the detail that IFC quantity sets require. It also allows many quantity set objects to share the same definition, rather than having the definition information duplicated on each quantity set object.
