mesh

Hi all,

I need your help!

Could u suggest me a method or a strategy to realize a mesh that has these features :
1- same sizes faces (facce tutte uguali!)
2- planar faces
3-quad faces
4-you can choice the directions of the isocurve of the mesh... and they have to be (maybe) the same directions of the principal directions of curvature

How I could be the 1-2-3 points? I know, the fourth it is not so easy!

thanks

GS
