A right-handed orthogonal Cartesian coordinate system. Used to define the vessel coordinate system definition., either in world coordinates (mandatory) or as additional local systems if necessary. CoordinateSystem has the following child elements:
| Child | Namespace | Type | Use | Cardinality | Choice | Description |
|---|---|---|---|---|---|---|
| LocalCartesian | ocx | ocx:Transformation_T | opt. | [0, 1] | False | 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) |
| XRefPlanes | ocx | ocx:RefPlanes_T | req. | [1, 1] | False | A collection of Y-Z planes used as object limits. Can also be used to create a frame table definition for display purposes. The exporting application will then have to provide all grid positions. |
| YRefPlanes | ocx | ocx:RefPlanes_T | opt. | [0, 1] | False | A collection of X-Z planes used as object limits. Can also be used to create a frame table definition for display purposes. The exporting application will then have to provide all grid positions. |
| ZRefPlanes | ocx | ocx:RefPlanes_T | opt. | [0, 1] | False | A collection of X-Y planes used as object limits. Can also be used to create a frame table definition for display purposes. The exporting application will then have to provide all grid positions. |
CoordinateSystem has the following attributes:
| Attribute | Namespace | Type | Use | Default | Fixed | Description |
|---|---|---|---|---|---|---|
| isGlobal | ocx | xs:boolean | optional | true | If set to true, the coordinate system is the global world coordinate frame with right-handed convention. This is the default. | |
| GUIDRef | ocx | ocx:guid | req. | A globally Unique ID referring an entity in the sending application. | ||
| name | ocx | xs:string | opt. | An optional descriptive or display name. | ||
| id | ocx | xs:ID | req. | An identifier for an element unique within the scope of the XML file. Each id must be unique within a document. The attribute uses the standard XML 1.0 ID type as defined in the XML Schema specification. This attribute is required in many OCX XML elements and an application should generate them automatically. |
