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. XRefPlanes has the following child elements:
| Child | Namespace | Type | Use | Cardinality | Choice | Description |
|---|---|---|---|---|---|---|
| RefPlane | ocx | ocx:RefPlane_T | req. | [1, ∞] | False | A reference plane used to define unbounded planar geometry. |
XRefPlanes has the following attributes:
| Attribute | Namespace | Type | Use | Default | Fixed | Description |
|---|---|---|---|---|---|---|
| isReversed | ocx | xs:boolean | opt. | false | For most vessels the X reference positions are given aft to forward which is the default. Set isReversed=true if the frame positions are given from fore to aft (normally this is the case for naval vessels). | |
| isMainSystem | ocx | xs:boolean | opt. | true | True if this is the main reference system definition. |
