Rule Name: Feature Edge Restrictions

Definition

1. The Locations within a Feature Edge must be distinct (i.e., no 2 may have the same coordinates).

2. Feature Edges may meet only at Feature Nodes, and Feature Faces may meet only along one or more Feature Edges.

3. At feature topology level 2 or higher, no Feature Edge may intersect with or overlap another Feature Edge.

4. At feature topology level 3, each Feature Edge forms part of the boundaries of exactly two Feature Faces.

Rationale

The path defined by the sequence of line segments which connect the consecutive Locations that make up a Feature Edge must not intersect or overlap itself.
