SurfaceCollection
A collection of any number of surfaces. The surfaces have to be connected (no dis-joint surfaces). Most typically the SurfaceCollection will include the outer shell geometry definition of the vessel.
Attributes
| Name | Type | Use | Description |
|---|---|---|---|
| GUIDRef | ocx:guid | optional | A globally unique ID referring to an entity in the authoring application. The sending application creates and holds the GUID. Used to establish a unique reference to an entity persistent between applications. |
| id | xs:ID | required | 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. |
| name | xs:string | optional | An optional descriptive or display name. |
Children
| Name | Type | Cardinality | Description |
|---|---|---|---|
| Cone3D | ocx:Cone3D_T | [1, ∞] | Definition of the Cone surface defined by origin, radius and position of the cone tip. |
| Cylinder3D | ocx:Cylinder3D_T | [1, ∞] | Definition of the cylindrical surface defined by root point, axis direction, radius and height. |
| ExtrudedSurface | ocx:ExtrudedSurface_T | [1, ∞] |
either a sweep direction and length or a sweep curve. |
| NURBSSurface | ocx:NURBSSurface_T | [1, ∞] | Non-uniform rational basis surface definition defined by a net (grid) of polynomial basis functions in U and V direction. |
| Plane3D | ocx:Plane3D_T | [1, ∞] | Definition of a Planar surface defined by Root Point and Normal. |
| Sphere3D | ocx:Sphere3D_T | [1, ∞] | Definition of a Spherical surface defined by origin and radius. |
| Description | xs:string | [0, 1] | Contains a description of the component its parent represents. The description is stored as a string. You can use this element for whatever purposes you require. This element can be used inside many OCX XML elements but is optional. |
| CustomProperties | ocx:CustomProperties_T | [0, 1] | Container for custom properties. |
