ABSTRACT This definition may not be instantiated
An IfcSweptSurface is a surface defined by sweeping a curve. The swept surface is defined by a open or closed curve, represented by a subtype if IfcProfileDef, that is provided as a two-dimensional curve on an implicit plane, and by the sweeping operation.
- The swept curve is defined by positioning the profile in the xy plane of the object coordinate system,
- The sweeping operation is applied to the swept curve as defined within the subtypes of IfcSweptSurface;
The optional _Positio_n coordinate system allows for re-positioning the resulting swept surface 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 space dimensionality of IfcSurface. It is always a three-dimensional geometric representation item.

The curve to be swept in defining the surface. The curve is defined as a profile within the position coordinate system.
Position coordinate system for the swept surface, provided by a profile definition within the XY plane of the Position coordinates. If not provided, the position of the profile being swept is determined by the object coordinate system. In this case, the swept surface is not repositioned.
