5.1.3.26.1 Semantic definition

The objectified relationship IfcRelAssignsToProcess handles the assignment of one or many objects to a process or activity. An object can be a product that is the item the process operates on. Processes and activities can operate on things other than products, and can operate in ways other than input and output.

The inherited attribute RelatedObjects gives the references to the objects, or object type, which the process operates on. The RelatingProcess is the process or process type, that operates on the object. The operation types are captured in the inherited attribute Name.
