The IfcFacetedBrep is a manifold solid brep with the restriction that all faces are planar and bounded polygons.
The faceted B-rep has been introduced in order to support the larger number of systems that allow boundary type solid representations with planar surfaces only.
- All the bounding loops of all the faces of all the shells in the IfcFacetedBrep shall be of type IfcPolyLoop.
- All vertices shall be referenced by all polyloops, sharing the vertex. I.e., each Cartesian point shall be references by at least three polyloops.
|LayerAssignment||SET [0:1] OF IfcPresentationLayerAssignment FOR AssignedItems||
Assignment of the representation item to a single or multiple layer(s). The LayerAssignments can override a LayerAssignments of the IfcRepresentation it is used within the list of Items.
|StyledByItem||SET [0:1] OF IfcStyledItem FOR Item||
Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve.

A closed shell defining the exterior boundary of the solid. The shell normal shall point away from the interior of the solid.
