ABSTRACT This definition may not be instantiated
The IfcPoint is the abstract generalisation of all point representations within a Cartesian 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 this abstract class, handled by a function specific for concrete subtypes. Determined by the number of coordinate components in case of IfcCartesianPoint or by the dimensionality of the basis curve or surface in other cases.
