ABSTRACT This definition may not be instantiated Semantic definition

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. Entity inheritance 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.

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.
