Add surface curve

Add surface curve adds another surface curve to a surface. You can then use the curve to modify the shape of the surface.

To use Add surface curve:

1. In the Modify Surface dialog, select Add surface curve.
2. Select a surface from the Surface list, or click the Pick Surface button and select it in the graphics window.
3. Click the Pick point on surface button and select a point in the graphics window.

   The coordinates of the point are displayed.

4. Select Row or Column to determine the orientation of the new curve.
5. Click OK.

This edit breaks the link between the surface and the method originally used to construct it. You cannot open the surface's Properties dialog and modify it based on the parameters that originally defined it as those parameters no longer apply directly to this surface.
