parametric folded plate structure PROBLEM!

Hi! I'm trying to make a parametric folded plate structure based on two adjacent surfaces. I use the graph mapper to create the form and then the graph mapper and iso-curves to create an uneven division across the surface. The resulting points are organised using a tree branch path mapping routine and then woven together to create an offset grid.

Can someone help me with some adjustments to diagrid method.. It's kinda making me crazy with this things.. Any help would be appreciated! Thx!
