[Gmsh] Ruled surface question

[Martin Vymazal]

Hi,

 one way that could possibly work would be to make each of the sub-segments a 
spline itself. Each surface bounded by 4 sub-segments would then be a ruled 
surface. This means that you would have to define a sufficient number of 
points (more than 2)  to determine the correct shape of each of the sub-
segment splines.

Best regards,
