7.2.3.11 IfcUnitaryControlElement

7.2.3.11.1 Semantic definition

A unitary control element combines a number of control components into a single product, such as a thermostat or humidistat.

A unitary control element provides a housing for an aggregation of control or electrical distribution elements that, in combination, perform a singular (unitary) purpose. Each item in the aggregation may have its own geometric representation and location.

7.2.3.11.4 Formal propositions

Name Description
CorrectPredefinedType

Either the PredefinedType attribute is unset (e.g. because an IfcUnitaryControlElementType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.

NOT(EXISTS(PredefinedType)) OR
(PredefinedType <> IfcUnitaryControlElementTypeEnum.USERDEFINED) OR
((PredefinedType = IfcUnitaryControlElementTypeEnum.USERDEFINED) AND EXISTS (SELF\IfcObject.ObjectType))
CorrectTypeAssigned

Either there is no unitary control element type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcUnitaryControlElementType.

(SIZEOF(IsTypedBy) = 0) OR
('IFC4X3_DEV_7e95fe8.IFCUNITARYCONTROLELEMENTTYPE' IN TYPEOF(SELF\IfcObject.IsTypedBy[1].RelatingType))

Last change: Improve definition split (#876) * bring back headers headers were previously removed by mistake, now bringing them back * add new lines and rename the tag add the word 'short' in it * unify newlines make exactly one newline before and two after the tag * resolving typos Because bringing back headers required to go back in time to previous version, I'm now re-resolving the issues: #861, #860, #856 by ArturTomczak on 7/16/2024, 2:07:28 PM
