28 | //! The abstract class MakeSweep is |
29 | //! the root class of swept primitives. |
30 | //! Sweeps are objects you obtain by sweeping a profile along a path. |
31 | //! The profile can be any topology and the path is usually a curve or |
32 | //! a wire. The profile generates objects according to the following rules: |
33 | //! - Vertices generate Edges |
34 | //! - Edges generate Faces. |
35 | //! - Wires generate Shells. |
36 | //! - Faces generate Solids. |
37 | //! - Shells generate Composite Solids. |
38 | //! You are not allowed to sweep Solids and Composite Solids. |
39 | //! Two kinds of sweeps are implemented in the BRepPrimAPI package: |
40 | //! - The linear sweep called a Prism |
41 | //! - The rotational sweep called a Revol |
42 | //! Swept constructions along complex profiles such as BSpline curves |
43 | //! are also available in the BRepOffsetAPI package.. |
