- Projection according to the Robot orientation.

- Projection normal to the surface.

The projected curves are Splines lying on the surface.
The converter wizard is automatically used to process the resulting
curve. It generates either a 2D NUPBS (Non Uniform Polynomial B-Spline) curve
identified by the Exact text, or a 3D NUPBS curve
(identified by Cv text).
If you want to further control the projected curve,
right-click the displayed text and choose the Edit
context menu. The converter wizard is then explicitly launched.
For example, in the case of a 2D curve, you may want to
generate a single segment curve. Select both
Segmentation and Single in
the Converter Wizard, then click OK.
