41//! Describes functions to build prism features.
42//! These can be depressions or protrusions.
43//! The semantics of prism feature creation is
44//! based on the construction of shapes:
45//! - along a length
46//! - up to a limiting face
47//! - from a limiting face to a height.
48//! The shape defining construction of the prism feature can be
49//! either the supporting edge or the concerned area of a face.
50//! In case of the supporting edge, this contour
51//! can be attached to a face of the basis shape by
52//! binding. When the contour is bound to this face,
53//! the information that the contour will slide on the
54//! face becomes available to the relevant class methods.
55//! In case of the concerned area of a face, you
56//! could, for example, cut it out and move it to a
57//! different height which will define the limiting
58//! face of a protrusion or depression.
