0034 //! from BRepTools. Some of  them have to be redefined
0035 //! if  the  modification is  implemented with another
0036 //! tool (see Transform from BRepBuilderAPI for example).
0037 //! The BRepBuilderAPI package provides the following
0038 //! frameworks to perform modifications of this sort:
0039 //! -   BRepBuilderAPI_Copy to produce the copy of a shape,
0040 //! -   BRepBuilderAPI_Transform and
0041 //! BRepBuilderAPI_GTransform to apply a geometric
0042 //! transformation to a shape,
0043 //! -   BRepBuilderAPI_NurbsConvert to convert the
0044 //! whole geometry of a shape into NURBS geometry,
0045 //! -   BRepOffsetAPI_DraftAngle to build a tapered shape.
