Hidden parts of a curve as dashed

Hi,

I need to draw a 3D curve on a surface with hidden parts. I want the
hidden parts of the curve to be drawn dashed. For this I use the method
descibed in

http://library.wolfram.com/mathgroup/archive/1995/May/msg00175.html

[Contact the author for the notbook file mentioned next - moderator]

As may be seen on the figure (see the attached file) the result is not
completely satisfactory because only a part of the hidden part of the
curve is dashed.

Is there a solution ?

Remark: in the attached file, the first cell computes the surface and I
kept the comments in French because I think you don't need to
understand  them. I translated the comments only in the graphics parts.

Thank you  for your help.
