IfcSimpleProperty is a generalization of a single property object. The various subtypes of IfcSimpleProperty establish different ways in which a property value can be set.
HISTORY New entity in IFC1.0, definition changed in IFC2x.
| # | Attribute | Type | Cardinality | Description | G |
|---|---|---|---|---|---|
| IfcPropertyAbstraction | |||||
| HasExternalReferences | IfcExternalReferenceRelationship @RelatedResourceObjects | S[0:?] | Reference to an external reference, e.g. library, classification, or document information, that is associated to the property definition.
IFC4 CHANGE New inverse attribute. | X | |
| IfcProperty | |||||
| 1 | Name | IfcIdentifier | Name for this property. This label is the significant name string that defines the semantic meaning for the property. | X | |
| 2 | Description | IfcText | ? | Informative text to explain the property. | X |
| PartOfPset | IfcPropertySet @HasProperties | S[0:?] | Reference to the IfcPropertySet by which the IfcProperty is referenced.
IFC4 CHANGE New inverse attribute to navigate from IfcProperty to IfcPropertySet with upward compatibility for file based exchange. | X | |
| PropertyForDependance | IfcPropertyDependencyRelationship @DependingProperty | S[0:?] | The property on whose value that of another property depends. | X | |
| PropertyDependsOn | IfcPropertyDependencyRelationship @DependantProperty | S[0:?] | The relating property on which the value of the property depends. | X | |
| PartOfComplex | IfcComplexProperty @HasProperties | S[0:?] | Reference to the IfcComplexProperty in which the IfcProperty is contained.
IFC4 CHANGE The cardinality has changed to 0..n to allow reuse of instances of IfcProperty in several IfcComplexProperty with upward compatibility for file based exchange. | X | |
| HasConstraints | IfcResourceConstraintRelationship @RelatedResourceObjects | ? S[0:?] | User-defined constraints for the property. | X | |
| HasApprovals | IfcResourceApprovalRelationship @RelatedResourceObjects | ? S[0:?] | User-defined approvals for the property. | X | |
