ContourPolyline2D defines a linear curve segment as part of a trimming contour in the u-v domain of a NURBS surface. NurbsCurve2D and ContourPolyline2D nodes that together form a closed contour, defined in the u-v parametric space of a NURBS surface, may be used as children in a Contour2D node.
The ContourPolyline2D node belongs to the NURBS component and requires at least level 3, its default container field is children. It is available from X3D version 3.0 or higher.

controlPoint specifies the end points of each segment of the piecewise linear curve.
- ContourPolyline2D is not a renderable geometry node.
