Hi gizmo - there's also some extra information on how to arrange the curves for Network here: http://moi3d.com/forum/index.php?webtag=MOI&msg=1905.1

For Network the curves need to be arranged in a particular way that can be unwrapped to a 2D grid pattern. If your curves are not arranged in that way then it will still get forced to be like that and you can get some strange results like your first one there.
