Definition from buildingSMART: The IfcControl
is the abstract generalization of all concepts that control or
constrain products or processes in general. It can be seen as a
specification, regulation, cost schedule or other requirement applied
to a product or process whose requirements and provisions must be
fulfilled. Controls are assigned to products, processes, or other
objects by using the IfcRelAssignsToControl
EXAMPLE Controls are e.g.,
space program, cost schedules, order, work plan, etc.
NOTE Some basic items,
such as cost value, approval, or constraint are directly attachable to
products and processes using the association relationship subtypes of IfcRelAssociates.
New entity in IFC Release 1.0.
|| Reference to the relationship that associates the control to the object(s) being controlled.
