class EqualDistanceRelation from AIS inherits Relation from AIS
---Purpose: A framework to display equivalent distances between
-- shapes and a given plane.
-- The distance is the length of a projection from the
-- shape to the plane.
-- These distances are used to compare shapes by this vector alone.
