4.8.2.1.1 Annotation 2D Geometry

The 'Annotation 2D Geometry' is used, when the representation of an annotation includes specific drafting representation elements, in particular areas for hatching and text.

The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

• IfcShapeRepresentation.RepresentationIdentifier : 'Annotation'
• IfcShapeRepresentation.RepresentationType : 'Annotation2D'
• IfcShapeRepresentation.Items :
  • subtypes of IfcPoint and IfcCurve being two-dimensional and within an IfcGeometricCurveSet
  • subtypes of IfcAnnotationFillArea for hatches
  • subtypes of IfcTextLiteral for text

Figure 59 illustrates an instance diagram.
