7.5.3.65.4 Formal propositions

Name Description
CorrectPredefinedType

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

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

Either there is no vibration isolator type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcVibrationIsolatorType.

(SIZEOF(IsTypedBy) = 0) OR
