- org.web3d.x3d.jsail.X3DConcreteElement
- - org.web3d.x3d.jsail.X3DConcreteNode
  - - org.web3d.x3d.jsail.NURBS.Contour2DObject

All Implemented Interfaces:

X3DNode, Contour2D
```
public class Contour2DObject
extends X3DConcreteNode
implements Contour2D
```
X3D node tooltip: Contour2D groups a set of curve segments into a composite contour. The children segments form a closed loop, with first point of first child repeated as last point of last child, and last point of each segment repeated as the first point of the next consecutive segment. The children segments are type NurbsCurve2D or ContourPolyline2D, enumerated in the consecutive order of contour topology.
- Warning: Contour2D is not a renderable geometry node.
- Hint: Contour2D is used as the trimmingContour field of the NurbsTrimmedSurface node.
Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile using the org.web3d.x3d.sai package instead.

  - setUSE
```
public final Contour2DObject setUSE(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named USE.
    
    Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value). Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance. Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute. Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.
    
    Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.
    
    WARNING: invoking the setUSE() method resets all other fields to their default values and also releases all child nodes.
    
    WARNING: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
