An IfcCartesianPoint defines a point by coordinates in an orthogonal, right-handed Cartesian coordinate system. For the purpose of this specification only two and three dimensional Cartesian points are used.
|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.

|1||Coordinates||LIST [1:3] OF IfcLengthMeasure||
The first, second, and third coordinate of the point location. If placed in a two or three dimensional rectangular Cartesian coordinate system, Coordinates is the X coordinate, Coordinates is the Y coordinate, and Coordinates is the Z coordinate.
Only two or three dimensional points are in scope.
