|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.
Connectivity between the continuous segments is not enforced per se to be tangential. Setting "TangentialContinuity" to True means that the current segment shall continue with tangential continuity to the previous one.
|UsingCurves||SET [1:?] OF IfcCompositeCurve FOR Segments||
The set of composite curves which use this composite curve segment as a segment. This set shall not be empty.
This attribute is formally derived.
The space dimensionality of this abstract class, handled by a function specific for concrete subtypes which returns the dimensionality of the ParentCurve attribute (defined on both subtypes).

An indicator of whether or not the sense of the segment agrees with, or opposes, that of the parent curve. If SameSense is false, the point with highest parameter value is taken as the first point of the segment.
The bounded curve which defines the geometry of the segment.
The parent curve shall be a bounded curve.
