Feature Edges
Feature Edge – a one-dimensional spatial entity that defines a path through 2D or 3D space
- The shape of an edge is defined by a sequence of two or more distinct 2D or 3D coordinate tuples
- The orientation of an edge is defined by the order of its coordinate tuples
An edge is bounded by a node at each of its two endpoints (conceptually, the endpoints are included in the edge, but they are not stored with it)
Edges may meet only at common nodes
- Edge interiors may not intersect one another (Exception: Feature Topology Levels 0 & 1)
An edge may be completely contained within a volume
