4.8.2.7.7 Body AdvancedBrep Geometry

The Body Brep Geometry is the representation of the 3D shape of a product by boundary representation models, including NURBS.

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

• IfcShapeRepresentation.RepresentationIdentifier = 'Body'
• IfcShapeRepresentation.RepresentationType = 'AdvancedBrep'
• IfcShapeRepresentation.Items = IfcAdvancedBrep, IfcFacetedBrep

Figure 80 illustrates an instance diagram.
