34 | //! Describes functions to build linear swept topologies, called prisms. |
35 | //! A prism is defined by: |
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 |
47 | //! A MakePrism object provides a framework for: |
48 | //! - defining the construction of a prism, |
49 | //! - implementing the construction algorithm, and |
50 | //! - consulting the result. |
