0027 //! The abstract class MakeSweep is
0028 //! the root class of swept primitives.
0029 //! Sweeps are objects you obtain by sweeping a profile along a path.
0030 //! The profile can be any topology and the path is usually a curve or
0031 //! a wire. The profile generates objects according to the following rules:
0032 //! -      Vertices generate Edges
0033 //! -      Edges generate Faces.
0034 //! -      Wires generate Shells.
0035 //! -      Faces generate Solids.
0036 //! -      Shells generate Composite  Solids.
0037 //! You are not allowed to sweep Solids and Composite Solids.
0038 //! Two kinds of sweeps are implemented in the BRepPrimAPI package:
0039 //! -      The linear sweep called a   Prism
0040 //! -      The rotational sweep    called a Revol
0041 //! Swept constructions along complex profiles such as BSpline curves
0042 //! are also available in the BRepOffsetAPI package..
