Notes

Associated with Notes

Geometry_Node

 For a given instance E of <Volume Object>, this corresponds
 to the <Location 3D> component of E.

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.

Location_3D

 For a given instance of <Volume Object>, this
 specifies the centre of the bottom face, where "bottom"
 is determined by the SRF in which the <Volume Object> is specified.
