Class Name: Geometry Edge
Subclasses
This DRM class is concrete and has no subclasses.
Definition
An instance of this DRM class is a one-dimensional
<Geometry Topology> instance
consisting of an ordered collection of
<Location> instances connecting one
<Geometry Node> instance to another
<Geometry Node> instance. The orientation of a
<Geometry Edge> instance is defined by the order
of its <Location> components, taken in
conjunction with
its starting <Geometry Node> instance and ending
<Geometry Node> instance.
A <Geometry Edge> instance is used to represent
the location of a segment of
one or more <Linear Geometry> instances and/or
a boundary of one or more
<Geometry Face> instances.

Example
A <Line> instance that represents the lighting of
a runway consists of two <Geometry Edge>
instances, representing the lights on each side of the runway.

Notes
Associated with Notes
If present, these <Geometry Face>
instances (if any exist) are those bordered by the
<Geometry Edge> instance, ordered
counterclockwise when looking along the
<Geometry Edge> instance.
The converse of this relationship is that between
<Geometry Face> instances and
<Geometry Edge> instances.
This association specifies that the
<Geometry Edge> instance is
bounded by these
<Geometry Node> instances.
The first <Geometry Node> instance
is the starting node of the
<Geometry Edge> instance, while the
second <Geometry Node> instance
is the ending node.
These <Geometry Volume> instances
are those that contain the <Geometry Edge>
instance.
