The objectified relationship IfcRelAssignsToGroupByFactor is a specialization of the general grouping mechanism. It allows to add a factor to define the ratio that applies to the assignment of object definitions (individual object occurrences as subtypes of IfcObject and object types as subtypes of IfcTypeObject) to a group (subtypes of IfcGroup).
