deferred class ModifyShape from BRepBuilderAPI inherits MakeShape from BRepBuilderAPI
---Purpose: Implements the methods of MakeShape for the
-- constant topology modifications. The methods are
-- implemented when the modification uses a Modifier
-- from BRepTools. Some of them have to be redefined
-- if the modification is implemented with another
-- tool (see Transform from BRepBuilderAPI for example).
-- The BRepBuilderAPI package provides the following
-- frameworks to perform modifications of this sort:
-- - BRepBuilderAPI_Copy to produce the copy of a shape,
-- - BRepBuilderAPI_Transform and
-- BRepBuilderAPI_GTransform to apply a geometric
-- transformation to a shape,
-- - BRepBuilderAPI_NurbsConvert to convert the
-- whole geometry of a shape into NURBS geometry,
-- - BRepOffsetAPI_DraftAngle to build a tapered shape.

---Purpose: Set the field <myModification> with <M>.

---Purpose: Returns the modified shape corresponding to <S>.
-- S can correspond to the entire initial shape or to its subshape.
-- Exceptions
-- Standard_NoSuchObject if S is not the initial shape or
-- a subshape of the initial shape to which the
-- transformation has been applied. Raises NoSuchObject from Standard
-- if S is not the initial shape or a sub-shape
-- of the initial shape.
