IfcTank: public Ifc4::IfcFlowStorageDevice¶
A tank is a vessel or container in which a fluid or gas is stored for later use.
HISTORY New entity in IFC2x4
Type Use Definition IfcTank defines the occurrence of any tank; common information about tank types is handled by IfcTankType. The IfcTankType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcTankType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcTankType has ports or aggregated elements, such objects are reflected at the IfcTank occurrence using the IfcRelDefinesByObject relationship.
Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcTankType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcTankType.HasPropertySets. If both are given, then the properties directly defined at IfcTank override the properties defined at IfcTankType. Refer to the documentation at the supertype IfcFlowStorageDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: (All Types)
Pset_TankOccurrence (PSET_OCCURRENCEDRIVEN) Pset_TankTypeCommon (PSET_TYPEDRIVENOVERRIDE)
Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.
Material Use Definition The material of the IfcTank is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcTankType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
Body: The primary material from which the object is constructed.
Port Use Definition The distribution ports relating to the IfcTank are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the tank occurrence is defined by IfcTankType, then the port occurrences must reflect those defined at the IfcTankType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcTank PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
Inlet (NOTDEFINED, SINK): Inlet. Outlet (NOTDEFINED, SOURCE): Outlet.
Whether the optional attribute PredefinedType is defined for this IfcTank.
