4.8.1.4.2.2 Body AdvancedSwept DiskSolid PolyCurve Geometry

The Body AdvancedSwept DiskSolid PolyCurve Geometry is the representation of the 3D shape of a product by swept disk solid models, where the directrix is created by an indexed poly curve.

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 tables below shows a recommended list of general usage patterns that users may adopt.
