IfcProperty is an abstract generalization for all types of properties that can be associated with IFC objects through the property set mechanism.
HISTORY New entity in IFC1.0.
# | Attribute | Type | Cardinality | Description | G |
---|---|---|---|---|---|
1 | Name | IfcIdentifier | Name for this property. This label is the significant name string that defines the semantic meaning for the property. | X | |
2 | Specification | 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 | |
PartOfMaterialOrProfileProperties | IfcExtendedProperties @Properties | S[0:?] | Reference to the IfcMaterialProperties by which the IfcProperty is referenced. | X |
