X3D node tooltip: [X3DGeometryNode] Arc2D is a line-based geometry node that defines a linear circular arc with center (0,0) in X-Y plane, with angles measured starting at positive x-axis and sweeping towards positive y-axis.
- Hint: Material emissiveColor in corresponding Appearance is used for rendering lines.
- Warning: lines are not lit, are not texture-mapped, and do not participate in collision detection.
- Warning: use a different Material emissiveColor than the Background color, otherwise geometry is invisible.
- Hint: adding LineProperties to the corresponding Appearance node can modify the rendering style of these lines.
- Hint: insert a Shape node before adding geometry or Appearance.
- Warning: requires X3D profile='Full' or else include <component name='Geometry2D' level='2'/> Example: X3D Example Archives, X3D for Web Authors, Chapter 10 Geometry 2D

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 separate code using only the org.web3d.x3d.sai package instead.

```
    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 on this node resets all other fields to their default values (except for containerField) 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.
