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

14 | class PlaneTrihedron from AIS inherits InteractiveObject from AIS |
15 | |
16 | ---Purpose: To construct a selectable 2d axis system in a 3d |
17 | -- drawing. This can be placed anywhere in the 3d |
18 | -- system, and provides a coordinate system for |
19 | -- drawing curves and shapes in a plane. |
20 | -- There are 3 selection modes: |
21 | -- - mode 0 selection of the whole plane "trihedron" |
22 | -- - mode 1 selection of the origin of the plane "trihedron" |
23 | -- - mode 2 selection of the axes. |
24 | -- Warning |
25 | -- For the presentation of planes and trihedra, the |
26 | -- millimetre is default unit of length, and 100 the default |
27 | -- value for the representation of the axes. If you modify |
28 | -- these dimensions, you must temporarily recover the |
29 | -- Drawer object. From inside it, take the Aspects in |
30 | -- which the values for length are stocked, for example, |
31 | -- PlaneAspect for planes and FirstAxisAspect for |
32 | -- trihedra. Change these values and recalculate the presentation. |
