EDGE (C004, C006, C008, C043, C109)

(Rules) (Express)

An edge is a curve in space bounded by zero, one or two vertices. An edge may also be a portion of a ring boundary between two vertices. In this case an edge is topologically a bounding curve segment which may serve as part of a ring boundary for one or more faces which meet at that edge. An edge is orientable, though not oriented.
