generic class SearchOnBoundaries from IntStart (
TheVertex as any;

-- of a surface (parametric or implicit), used through
-- the classes TheArcTool, TheSOBTool and TheTopolTool,
-- and an implicit surface (natural quadric : Pln, Cylinder,
-- Cone, Sphere from gp)..

-- TolBoundary defines if a curve is on Q.
-- TolTangency defines if a point is on Q.

-- of an arc of the domain is infinite. See the method Bounds
-- of the class SOBTool.
