    IfcFlowMovingDeviceType

    实体定义

    元素类型IfcFlowMovingDeviceType定义了流移动设备的公共共享属性集定义列表和一组可选的产品表示。它用于定义流量移动设备规范(即特定产品信息,该产品类型的所有实例通用)。

    流动类型用于定义流动设备的公共属性,该属性可应用于该类型的多个实例。流量移动装置是用于在分配系统(如泵、风扇或压缩机)中产生压差的装置。可以交换流移动类型(或可实例化子类型),而无需将其指定给引用。

    IfcFlowMovingDeviceType的出现由IfcFlowMovingDevice或其子类型的实例表示。

    IFC2x2中的新实体。

    #AttributeTypeCardinalityDescriptionC
    IfcRoot
    1 GlobalId IfcGloballyUniqueId [1:1] Assignment of a globally unique identifier within the entire software world. X
    2 OwnerHistory IfcOwnerHistory [0:1] Assignment of the information about the current ownership of that object, including owning actor, application, local identification and information captured about the recent changes of the object,
    NOTE  only the last modification in stored - either as addition, deletion or modification.
    X
    3 Name IfcLabel [0:1] Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule. X
    4 Description IfcText [0:1] Optional description, provided for exchanging informative comments. X
    IfcObjectDefinition
      HasAssignments IfcRelAssigns
    @RelatedObjects
    S[0:?] Reference to the relationship objects, that assign (by an association relationship) other subtypes of IfcObject to this object instance. Examples are the association to products, processes, controls, resources or groups. X
      Nests IfcRelNests
    @RelatedObjects
    S[0:1] References to the decomposition relationship being a nesting. It determines that this object definition is a part within an ordered whole/part decomposition relationship. An object occurrence or type can only be part of a single decomposition (to allow hierarchical strutures only). X
      IsNestedBy IfcRelNests
    @RelatingObject
    S[0:?] References to the decomposition relationship being a nesting. It determines that this object definition is the whole within an ordered whole/part decomposition relationship. An object or object type can be nested by several other objects (occurrences or types). X
      HasContext IfcRelDeclares
    @RelatedDefinitions
    S[0:1] References to the context providing context information such as project unit or representation context. It should only be asserted for the uppermost non-spatial object. X
      IsDecomposedBy IfcRelAggregates
    @RelatingObject
    S[0:?] References to the decomposition relationship being an aggregation. It determines that this object definition is whole within an unordered whole/part decomposition relationship. An object definitions can be aggregated by several other objects (occurrences or parts). X
      Decomposes IfcRelAggregates
    @RelatedObjects
    S[0:1] References to the decomposition relationship being an aggregation. It determines that this object definition is a part within an unordered whole/part decomposition relationship. An object definitions can only be part of a single decomposition (to allow hierarchical strutures only). X
      HasAssociations IfcRelAssociates
    @RelatedObjects
    S[0:?] Reference to the relationship objects, that associates external references or other resource definitions to the object.. Examples are the association to library, documentation or classification. X
    IfcTypeObject
    5 ApplicableOccurrence IfcIdentifier [0:1] The attribute optionally defines the data type of the occurrence object, to which the assigned type object can relate. If not present, no instruction is given to which occurrence object the type object is applicable. The following conventions are used:
    • The IFC entity name of the applicable occurrence using the IFC naming convention, CamelCase with IFC prefix
    • It can be optionally followed by the predefined type after the separator "/" (forward slash), using uppercase
    • If one type object is applicable to many occurrence objects, then those occurrence object names should be separate by comma "," forming a comma separated string.
    EXAMPLE Refering to a furniture as applicable occurrence entity would be expressed as 'IfcFurnishingElement', refering to a brace as applicable entity would be expressed as 'IfcMember/BRACE', refering to a wall and wall standard case would be expressed as 'IfcWall, IfcWallStandardCase'.
    X
    6 HasPropertySets IfcPropertySetDefinition S[1:?] Set list of unique property sets, that are associated with the object type and are common to all object occurrences referring to this object type. X
      Types IfcRelDefinesByType
    @RelatingType
    S[0:1] Reference to the relationship IfcRelDefinedByType and thus to those occurrence objects, which are defined by this type. X
    IfcTypeProduct
    7 RepresentationMaps IfcRepresentationMap ~L[1:?] List of unique representation maps. Each representation map describes a block definition of the shape of the product style. By providing more than one representation map, a multi-view block definition can be given. X
    8 Tag IfcLabel [0:1] The tag (or label) identifier at the particular type of a product, e.g. the article number (like the EAN). It is the identifier at the specific level. X
      ReferencedBy IfcRelAssignsToProduct
    @RelatingProduct
    S[0:?] Reference to the IfcRelAssignsToProduct relationship, by which other products, processes, controls, resources or actors (as subtypes of IfcObjectDefinition) can be related to this product type. X
    IfcElementType
    9 ElementType IfcLabel [0:1] The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute 'PredefinedType' is set to USERDEFINED. X
    IfcDistributionElementType
    IfcDistributionFlowElementType
    IfcFlowMovingDeviceType
     

    EXPRESS Specification

    ENTITY IfcFlowMovingDeviceType
     ABSTRACT SUPERTYPE OF(ONEOF(IfcCompressorType, IfcFanType, IfcPumpType))
     SUBTYPE OF (IfcDistributionFlowElementType);
    END_ENTITY;
