48 //! Create a selectable trihedron
49 //! there are 4 modes of selection :
50 //! mode = 0 to select triedron ,priority = 1
51 //! mode = 1 to select its origine ,priority = 5
52 //! mode = 2 to select its axis ,priority = 3
53 //! mode = 3 to select its planes ,priority = 2
54 //! a trihedron has 1 origine,3 axes,3 planes.
56 //! For the presentation of trihedra, the default unit of
57 //! length is the millimetre, and the default value for the
58 //! representation of the axes is 100. If you modify these
59 //! dimensions, you must temporarily recover the Drawer.
60 //! From inside it, you take the aspect in which the values
61 //! for length are stocked. For trihedra, this is
62 //! Prs3d_Drawer_FirstAxisAspect. You change the
63 //! values inside this Aspect and recalculate the presentation.
64 //! If you want to use extended selection modes, different than 0,
65 //! you should take care of removing of the shapes from the interactive
66 //! context that has been computed for selection; it might be necessary
67 //! when you change selection mode. You can use methods Axis, Point,
68 //! Plane to retrieve the shapes.
