package StepToTopoDS

    --- Purpose: This package implements the mapping between AP214
    --  Shape representation and  CAS.CAD Shape Representation.
    --  The source schema is Part42 (which is included in AP214)

uses TopoDS, StdFail, TCollection, TColStd, BRep, Geom, Geom2d,
     GeomAdaptor, Extrema, gp, Transfer, Geom2dAPI,
     StepRepr, StepGeom, StepShape, TopTools
