Assigns to Control

Overview

Describes a relationship in which a set of objects are assigned to a control.
The control may be applied for various general purposes including:

Approval
Orders
Permits
Service Life
Condition assessment
etc.
Note that a number of control assignments are dealt with explicitly as functional parts.

Declares the assignment of a collection of objects to a control

Description	Entity/Pset/Functional Part	MAN	REC	OPT
Create the control to which entities will be related and the entities that will be related to it.
Set the occurrence of the parent product in the relationship Any subtype of IfcControl may act as the relating control in the relationship	IfcControl<parent subtypes>
Set the occurrences of the child entities in the relationship	IfcObject <child subtypes>
Assert the attributes of the relationship
Assert the parent relationship	IfcRelAssignsToControl.RelatingControl::IfcGroup <subtype>
Assert the child relationship	IfcRelAssignsToControl.RelatedObjects::IfcObject <subtypes>
Assert the type of related objects from the predefined list if required This value can be used to identify the parent supertype of related objects as e.g. product, group, process, control etc. If the related objects have mixed supertypes, then the value .NOTDEFINED. should be used.	IfcRelAssignsToControl.RelatedObjectsType::IfcObjectTypeEnum
Assert the identity of the relationship	IfcRelAssignsToControl.GlobalId::IfcGloballyUniqueId
Assert the owner history of the relationship	IfcRelAssignsToControl.OwnerHistory::fp_apply_owner_history
Specify a name of the relationship	IfcRelAssignsToControl.Name
Specify a description of the relationship	IfcRelAssignsToControl.Description
