| Name | Value | Description | 
|---|---|---|
| None | 0 | The convention for the rotation angles is not set. | 
| XYZ | 1 | The convention for the rotation angles is X - Y` - Z``. | 
| ZYX | 2 | The convention for the rotation angles is Z - Y` - X``. | 
| ZXY | 3 | The convention for the rotation angles is Z - X` - Y``. | 
Execution sequence of the rotation angles of an orientation of a coordinate system:
In this example, the orientation convention is ET_OrientationConvention.XYZ.
| 1 | Rotation of the coordinate system CS1 around its X axis. This creates the coordinate system CS2. | 
 
| 2 | Rotation of the coordinate system CS2 around its Y axis. This creates the coordinate system CS3. | 
 
| 3 | Rotation of the coordinate system CS3 around its Z axis. This creates the coordinate system CS4. |
