To specify a Local (Orthogonal) Axis System Origin and two of the local X,Y,Z axis need to be specified. When used to specify a Plane the XY (UV) plane is considered. Optional if the coordinate system is referring to the global coordinate frame (world coordinates) LocalCartesian 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. |
