class DiameterDimension from AIS inherits Relation from AIS
---Purpose: A framework to display diameter dimensions.
-- A diameter is displayed with arrows and text. The
-- text gives the length of the diameter.
-- The algorithm takes a length along a face and
-- analyzes it as an arc. It then reconstructs the circle
-- corresponding to the arc and calculates the
-- diameter of this circle. This diameter serves as a
-- relational reference in 3d presentations of the surface.
