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.

|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.
This attribute is formally derived.
The space dimensionality of this class, determined by the number of coordinates in the List of Coordinates.
Only two or three dimensional points are in scope.
