Return Value

The handle to the IfcOwnerHistory for the file.

IfcOwnerHistory defines all history and identification related information. In order to provide fast access it is directly attached to all independent objects, relationships and properties. IfcOwnerHistory is used to identify the creating and owning application and user for the associated object, as well as capture the last modifying application and user. Currently in Revit export to IFC, there is one owner history for the entire file with some default (for the file) values.
