4.1.7.1.4.8.4 Body SweptSolid PolyCurve Geometry

The Body SweptSolid PolyCurve Geometry is the representation of the 3D shape of a product by swept solid models, only allowing for the basic extruded area solids and revolved area solids.

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

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the table below shows a recommended list of general usage patterns that users may adopt.
