7.8.3.1 IfcRail

7.8.3.1.1 Semantic definition

A rail is a predominately linear built element that has a special section profile. Rail is distinctive from built elements with similar geometric shapes (e.g. beam, member) that its major function is to ensure guidance of moving for vehicles or other kinds of machineries.

7.8.3.1.4 Formal propositions

Name Description
CorrectPredefinedType

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

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

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

(SIZEOF(IsTypedBy) = 0) OR
('IFC4X3_DEV_54a9de1b.IFCRAILTYPE' IN TYPEOF(SELF\IfcObject.IsTypedBy[1].RelatingType))
