IfcTypeProduct defines a type definition of a product without being already inserted into a project structure (without having a placement), and not being included in the geometric representation context of the project. It is used to define a product specification, that is, the specific product information that is common to all occurrences of that product type.
An IfcTypeProduct may have a list of property set attached and an optional set of product representations. Values of these properties and the representation maps are common to all occurrences of that product type. The type-occurrence relationship is realized using the objectified relationship IfcRelDefinesByType.
NOTE The product representations are defined as representation maps, which may be assigned by a product instance through the representation item(s) being an IfcShapeRepresentation and having Items of type IfcMappedItem.
The representations at the occurrence level (represented by subtypes of IfcProduct) can override the specific representations at the type level:
An IfcTypeProduct may be exchanged without being already assigned to subtypes of IfcProduct.
HISTORY New entity in IFC2x.
IFC4 CHANGE The entity IfcTypeProduct shall not be instantiated from IFC4 onwards. It will be changed into an ABSTRACT supertype in future releases of IFC.
# | Attribute | Type | Cardinality | Description | B |
---|---|---|---|---|---|
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 | - | This attribute is out of scope for this model view definition and shall not be set. | ||
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. |
Rule | Description |
---|---|
ApplicableOccurrence | The product type (or style), if assigned to an object, shall only be assigned to object being a sub type of IfcProduct. |

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). | ||
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. | ||
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 | |

6 | HasPropertySets | IfcPropertySetDefinition | S[1:?] |
Set | X |
Types | IfcRelDefinesByType @RelatingType | S[0:1] | Reference to the relationship IfcRelDefinedByType and thus to those occurrence objects, which are defined by this type. | ||
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 | - | This attribute is out of scope for this model view definition and shall not be set. | ||
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. |
