17 | -- GG : GER61351 17/11/1999 Change SetColor() with a compatible Quantity_Color instead |
18 | -- the restricted NameOfColor. |
19 | -- SAV : OCC218 06/03/02 : Added two fields and methods to be able to change |
20 | -- axes labels. |
21 | -- X/YAxis() returns AIS_Line instead of AIS_Axis |

24 | class PlaneTrihedron from AIS inherits InteractiveObject from AIS |
25 | |
26 | ---Purpose: To construct a selectable 2d axis system in a 3d |
27 | -- drawing. This can be placed anywhere in the 3d |
28 | -- system, and provides a coordinate system for |
29 | -- drawing curves and shapes in a plane. |
30 | -- There are 3 selection modes: |
31 | -- - mode 0 selection of the whole plane "trihedron" |
32 | -- - mode 1 selection of the origin of the plane "trihedron" |
33 | -- - mode 2 selection of the axes. |
34 | -- Warning |
35 | -- For the presentation of planes and trihedra, the |
36 | -- millimetre is default unit of length, and 100 the default |
37 | -- value for the representation of the axes. If you modify |
38 | -- these dimensions, you must temporarily recover the |
39 | -- Drawer object. From inside it, take the Aspects in |
40 | -- which the values for length are stocked, for example, |
41 | -- PlaneAspect for planes and FirstAxisAspect for |
42 | -- trihedra. Change these values and recalculate the presentation. |
