[xcrysden] 2D cuts of the Fermi surface

[Suman Hossain]

Dear Xcrysden Community,

I've been using the nice Xcrysden Fermi surface viewer for a while
which is absolutely fantastic. It is meant to generate 3D surfaces.
But now I need to make certain 2D cuts of the Fermi surface I already  
made.
It is obvious that I should edit the case.klist or the case.in0 file  
and pick
only those k-points that belong to the 2D plane I want but for my  
system it is
becoming very complicated and I begin to wonder whether I'm missing
something.

Was there any discussion about generating 2D cuts of the Fermi  
surface before?
Is there any instructions on how to effectively edit the case.klist/ 
case.in0 file?

Please let me know and Thanks!

Suman.
