class PerpendicularRelation from AIS inherits Relation from AIS
---Purpose: A framework to display constraints of perpendicularity
-- between two or more interactive datums. These
-- datums can be edges or faces.

Create (aFShape : Shape from TopoDS;

---Purpose: Constructs an object to display constraints of
-- perpendicularity on shapes.
-- This object is defined by a first shape aFShape, a
-- second shape aSShape, and a plane aPlane.
-- aPlane is the plane of reference to show and test the
-- perpendicular relation between two shapes, at least
-- one of which has a revolved surface.
