8.8.3.10 IfcCartesianPointList3D
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.
