27 //! To construct a selectable 2d axis system in a 3d
28 //! drawing. This can be placed anywhere in the 3d
29 //! system, and provides a coordinate system for
30 //! drawing curves and shapes in a plane.
31 //! There are 3 selection modes:
32 //! - mode 0 selection of the whole plane "trihedron"
33 //! - mode 1 selection of the origin of the plane "trihedron"
34 //! - mode 2 selection of the axes.
36 //! For the presentation of planes and trihedra, the
37 //! millimetre is default unit of length, and 100 the default
38 //! value for the representation of the axes. If you modify
39 //! these dimensions, you must temporarily recover the
40 //! Drawer object. From inside it, take the Aspects in
41 //! which the values for length are stocked, for example,
42 //! PlaneAspect for planes and LineAspect for
43 //! trihedra. Change these values and recalculate the presentation.
