Figure 247 — Reference SweptSolid PolyCurve Geometry
The Reference SweptSolid PolyCurve Geometry is the reference representation of the 3D shape of a product by swept solid models, only allowing for the basic extruded area solids and revolved area solids. Being a reference representation it is normally not displayed and it is not used in a voiding relationship.
The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:
Figure 247 illustrates an instance diagram.
