A concept specifying a local (orthogonal) axis system. The Origin and two of the local X,Y,Z axis have to be specified. When used to specify a Plane the XY (UV) plane is considered. The third axis is found by the cross product of the primary and secondary axis. Transformation has the following child elements:
| Child | Namespace | Type | Use | Cardinality | Choice | Description |
|---|---|---|---|---|---|---|
| Origin | ocx | ocx:Point3D_T | req. | [1, 1] | False | The origin of a local or global coordinate system. |
| PrimaryAxis | ocx | ocx:Vector3D_T | req. | [1, 1] | False | The unit vector of the local X-axis (U-Axis) given in global Coordinate System. |
| SecondaryAxis | ocx | ocx:Vector3D_T | req. | [1, 1] | False | The unit vector of the local Y-axis (V-Axis) given in global Coordinate System. |
