I tried this. The best results are obtained with a step size of 0.01 
cell length on my data,and I get always short peaces of surface streamlines.
I discovered that the grid refinement was also an important parameter:
- when the grid is coarse at the seed point location, the surface 
streamline stops after crossing only one or two cells.
- when the grid is well refined at the seed point location, the surface 
streamline is longer and propagates over many cells, but it never 
reaches the boundary of the surface.

So I think that the best workaround is to put many seed points all over 
the surface. If someone has a better idea...

Best regards.
