class AngleDimension from AIS inherits Relation from AIS
---Purpose: A framework to define display of angles.
-- These displays are particularly useful in viewing draft prisms.
-- The angle displayed may define an intersection
-- can be between two edges or two faces of a shape
-- or a plane. The display consists of arrows and text.
