FreeEdgeCurve3D
A single Curve3D or a collection of continuous non-closed Curve3D types which are used to represent a free edge of a panel or plate in shipbuilding. FreeEdgeCurve3D has the following child elements:
| Child | Namespace | Type | Use | Cardinality | Choice | Description |
|---|---|---|---|---|---|---|
| Circle3D | ocx | ocx:Circle3D_T | req. | [1, ∞] | False | A circle in 3D space. |
| CircumArc3D | ocx | ocx:CircumArc3D_T | req. | [1, ∞] | False | 3D Line/Arc representation. Represents a semicircle uniquely defined by three points in 3D space given by the start position, intermediate position and the end position.. |
| CircumCircle3D | ocx | ocx:CircumCircle3D_T | req. | [1, ∞] | False | Definition of a circle in 3D space by a circum-circle of 3 points. |
| CompositeCurve3D | ocx | ocx:CompositeCurve3D_T | req. | [1, ∞] | False | The concept of a composite curve composed of a collection of Line3D, CircumArc3D and/or NURBS segments. Curves are sorted end to end and have C0 continuity across each segment in the CompositeCurve3D definition. |
| Ellipse3D | ocx | ocx:Ellipse3D_T | req. | [1, ∞] | False | An ellipse in 3D space. |
| Line3D | ocx | ocx:Line3D_T | req. | [1, ∞] | False | A straight line defined by two points. |
| NURBS3D | ocx | ocx:NURBS3D_T | req. | [1, ∞] | False | Non-Uniform Rational Spline Base curve definition. |
| PolyLine3D | ocx | ocx:PolyLine3D_T | req. | [1, ∞] | False | A list of 3D points defining a sequence of linear segments. Repeat the first position at the end of the last line segment to form a closed contour. |
FreeEdgeCurve3D has the following attributes:
| Attribute | Namespace | Type | Use | Default | Fixed | Description |
|---|---|---|---|---|---|---|
| isUVSpace | ocx | xs:boolean | opt. | false | Default is “false”. Set this attribute to true if the FreeEdgeCurve is represented by coordinates in the UV space. This should only be used when a FreeEdgeCurve is used to trim NURBS surface patches where the trim curve is only used to trim the underlying surface. When the curve is given in UV space, the X,Y point coordinates are replaced with the U,V coordinates. In this case the Z coordinate should be set to zero. The Z coordinate will not be used by the importing application. | |
| is2D | ocx | xs:boolean | opt. | false | Set to True if the Curve3D is given in 2D space. | |
| GUIDRef | ocx | ocx:guid | opt. | 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. | ||
| 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. |
