The IfcMappedItem is the inserted instance of a source definition (to be compared with a block / shared cell / macro definition). The instance is inserted by applying a Cartesian transformation operator as the MappingTarget.
NOTE A mapped item is a subtype of representation item. It enables a representation to be used as a representation item in one or more other representations. The mapped item allows for the definition of a representation using other representations.
NOTE Definition according to ISO/CD 10303-43:1992
A mapped item is a type of representation item that specifies the mapping of a representation as an element of the items of a second representation.
NOTE Entity adapted from mapped_item defined in ISO 10303-43.
HISTORY New entity in IFC2x.
|LayerAssignment||SET [0:1] OF IfcPresentationLayerAssignment FOR AssignedItems||Assignment of the representation item to a single or multiple layer(s). The LayerAssignments can override a LayerAssignments of the IfcRepresentation it is used within the list of Items.|
> IFC2x3 CHANGE The inverse attribute LayerAssignments has been added.
> IFC4 CHANGE The inverse attribute LayerAssignment has been restricted to max 1. Upward compatibility for file based exchange is guaranteed.
|StyledByItem||SET [0:1] OF IfcStyledItem FOR Item||Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve.|
> IFC2x3 CHANGE The inverse attribute StyledByItem has been added.
|1||MappingSource||IfcRepresentationMap||A representation map that is the source of the mapped item. It can be seen as a block (or cell or marco) definition.|
|2||MappingTarget||IfcCartesianTransformationOperator||A representation item that is the target onto which the mapping source is mapped. It is constraint to be a Cartesian transformation operator.|
