8.8.3.10.1 Semantic definition

The IfcCartesianPointList3D defines an ordered collection of three-dimentional Cartesian points. Each Cartesian point is provided as an three-dimensional point by a fixed list of three coordinates. The attribute CoordList is a two-dimensional list, where

first dimension is an unbounded list representing each 3D Cartesian point;
second dimension is a fixed list of three list members, where [1] is the x-coordinate, [2] the y-coordinate and [3] the z-coordinate of the Cartesian point.

8.8.3.10.3 Attributes

#	Attribute	Type	Description
IfcRepresentationItem (2)
	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. IFC2x3-CHANGE The inverse attribute LayerAssignments has been added. IFC4-CHANGE The inverse attribute LayerAssignment has been restricted to max 1. Upward compatibility for file based exchange is guaranteed.
	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. IFC2x3-CHANGE The inverse attribute StyledByItem has been added.
IfcCartesianPointList (1)
*	Dim	IfcDimensionCount	This attribute is formally derived. `IfcPointListDim(SELF)` The space dimensionality of this class, either 2 or 3, depending on the sub type.
