Notes

Associated with Notes

Geometry_Node

 A <Geometry Node> associated with a <Point> instance
 represents the topology of that <Point>.

Composed of Notes

Union_Of_Primitive_Geometry

 A <Primitive Geometry> instance contains a
 <Union Of Primitive Geometry> instance as a component only
 when that <Primitive Geometry> instance can be decomposed
 into nested <Primitive Geometry> instances, as (for
 example) a <Polygon> instance can be decomposed into
 subfaces.
