22 ---Purpose: This package describes a persistent Boundary
23 -- Representation Data Structure inherited from the
24 -- abstract Topology defined in the PTopoDS package.
25 -- The geometric data are provided by the PGeom and
29 gp, -- Elementary geometry
30 PTopLoc, -- Local coordinate systems
31 TopAbs, -- Enumerations : Orientation, ShapeType
32 PTopoDS, -- Abstract topological data structure
33 GeomAbs, -- Enumerations : Shape
34 PGeom, -- 3D geometry : curves and surfaces
35 PGeom2d, -- 2D geometry : curves in parametric space
36 PPoly, -- Persistent Triangulations and Polygons
37 PColStd -- Persistent Standard Collection
