[Gmsh] About Extrusion (one more time)

[Cécile Giorla]

Hi,
In a previous post ( http://www.geuz.org/pipermail/gmsh/2006/002230.html 
) you suggest to add the number of the lateral surfaces at the end of 
the vector (where vector = Extrude(,,){...}). I am very interested in 
this functionality. Or maybe you can give me another way to get a 
Physical Surface made by only these lateral surfaces.
By the way, the 2.0.5 on windows version is great : the Delaunay 
algorithm doesn't crash anymore. You really did good !
