ABSTRACT This definition may not be instantiated
IfcCsgPrimitive3D is an abstract supertype of all three dimensional primitives used as either tree root item, or as Boolean results within a CSG solid model. All 3D CSG primitives are defined within a three-dimensional placement 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.

The placement coordinate system to which the parameters of each individual CSG primitive apply.
This attribute is formally derived.
The space dimensionality of this geometric representation item, it is always 3.
