class ConcentricRelation from AIS inherits Relation from AIS

	---Purpose: A framework to define a constraint by a relation of
    	-- concentricity between two or more interactive datums.
    	-- The display of this constraint is also defined.
    	-- A plane is used to create an axis along which the
    	-- relation of concentricity can be extended.
