ABSTRACT This definition may not be instantiated
An IfcSweptAreaSolid represents the 3D shape by a sweeping representation scheme allowing a two dimensional planar cross section to sweep through space.
The swept area is defined by a cross section, represented by a subtype if IfcProfileDef, that is provided as a closed two-dimensional boundary on an implicit plane. The swept area is defined in the xy plane of the object coordinate system. The sweeping operation is applied to the swept area as defined within the subtypes of IfcSweptAreaSolid, some subtypes require an implicit transformation of the swept area to the start position of the sweep.
The optional Position coordinate system allows for re-positioning the resulting swept solid relative to the object coordinate system.
|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.
This attribute is formally derived.

The surface defining the area to be swept. It is given as a profile definition within the xy plane of the position coordinate system.
Position coordinate system for the resulting swept solid of the sweeping operation. The position coordinate system allows for re-positioning of the swept solid. If not provided, the swept solid remains within the position as determined by the cross section or by the directrix used for the sweeping operation.
The profile definition for the swept area solid shall be of type AREA.
