package BndLib
---Purpose: The BndLib package provides functions to add a geometric primitive to a bounding box.
-- Note: these functions work with gp objects, optionally
-- limited by parameter values. If the curves and surfaces
-- provided by the gp package are not explicitly
-- parameterized, they still have an implicit parameterization,
-- similar to that which they infer for the equivalent Geom or Geom2d objects.
-- Add : Package to compute the bounding boxes for elementary
-- objects from gp in 2d and 3d .
--
-- AddCurve2d : A class to compute the bounding box for a curve
-- in 2d dimensions ;the curve is defined by a tool
--
-- AddCurve : A class to compute the bounding box for a curve
-- in 3d dimensions ;the curve is defined by a tool
--
-- AddSurface : A class to compute the bounding box for a surface.
-- The surface is defined by a tool for the geometry and another
-- tool for the topology (only the edges in 2d dimensions)
---Level : Public.
-- All methods of all classes will be public.
