| 36 | //! - a basis shape, which is swept, and |
| 37 | //! - a sweeping direction, which is: |
| 38 | //! - a vector for finite prisms, or |
| 39 | //! - a direction for infinite or semi-infinite prisms. |
| 40 | //! The basis shape must not contain any solids. |
| 41 | //! The profile generates objects according to the following rules: |
| 42 | //! - Vertices generate Edges |
| 43 | //! - Edges generate Faces. |
| 44 | //! - Wires generate Shells. |
| 45 | //! - Faces generate Solids. |
| 46 | //! - Shells generate Composite Solids |

| 48 | //! - defining the construction of a prism, |
| 49 | //! - implementing the construction algorithm, and |
| 50 | //! - consulting the result. |
