[Gmsh] Reversal of extruded face normal direction

[Mark Starnes]

Hi everyone,

Is is possible to reverse the face normal of the
surface generated from a spline extrusion,
during the extrude command?  At the moment 
I'm having to extrude a spline; delete the surface; 
and re-create the surface with the lines generated
by the original extrusion.  Even then, I'm not
sure the surface curvature is correctly
generated.  I'm hoping for a keyword like,
`Recombine;', say, `Reverse;'.

Thanks in advance,

Mark.
