Class Name: Geometry Node

Superclass - <Geometry Topology>

Subclasses

Definition

An instance of this DRM class specifies a topological attribute that identifies a significant place, or the connecting point of higher-dimensional topological attribute(s). It is the component of one (or more) objects that have a single Location. The location of a Geometry Node is the same location as the spatially located object of which the node is a component.
