class Ifc4x3_rc1::IfcStyledItem : public Ifc4x3_rc1::IfcRepresentationItem

Definition from ISO/CD 10303-46:1992: The styled item is an assignment of style for presentation to a geometric representation item as it is used in a representation.

NOTE Corresponding ISO 10303 name: styled_item. Please refer to ISO/IS 10303-46:1994 for the final definition of the formal standard.

The IfcStyledItem holds presentation style information for products, either explicitly for an IfcGeometricRepresentationItem being part of an IfcShapeRepresentation assigned to a product, or by assigning presentation information to IfcMaterial being assigned as other representation for a product.

If the IfcStyledItem is used within a reference from an IfcProductDefinitionShape then one Item shall be provided. If the IfcStyledItem is used within a reference from an IfcMaterialDefinitionRepresentation then no Item shall be provided.

HISTORY New entity in IFC2x2.

IFC2x2 Addendum 1 CHANGE The entity IfcStyledItem has been made non abstract and the attribute Name added.

IFC2x3 CHANGE The attribute Item has been made optional, upward compatibility for file based exchange is guaranteed.

IFC2x4 CHANGE The subtype IfcAnnotationOccurrence and its subtypes are deleted. Use IfcStyledItem for all instantiations. The data type of Styles has been changed to IfcStyleAssignmentSelect

Use Definition

Figure 293 illustrates use of IfcStyledItem for the two usage examples:

As a presentation for a geometric representation item As a presentation for a material definition

NOTE The new IfcStyleAssignmentSelect allows the direct assignment styles, such as IfcCurveStyle, IfcSurfaceStyle without using the intermediate IfcPresentationStyleAssignment
