fabrication problems with waffel system

hello everybody,
i try to start with grasshopper but i am not a programmer or something like that- just a young artist. To start with this nice tool i made a short -kick start workshop- with the attached rhino file and i want to realize this form with the grasshopper definition from liftarchitects (Waffle Structural System.ghx ) to understand the backround of parametric design.
and now, there are some questions and problems to solve:

problem 1:why is there so much chaos with the Projected X Strut Curves especially on x strut 20
t
problem 2:why are they not on the cplane like the Projected Y Strut Curves

problem 3:when i compare the Projected Strut Curves with the Original Solid Struts,
the notches are not equal (is this just an interpolation thing - maybe i get in trouble with the connections of the x and y struts, if i want to lasercut the ribs)

problem 4:is it possible on an easy way to extrude the top srf of the Original Solid X Struts and the bottom srf of the Original Y Solid Struts by a slider

It would be great if someone could help me
thanx in advance
frankie

The reason you're having issues is that that file was originally written for ver. 0.5.0099 which did not have the ability to use data structures. You could of course re-install the old version and it should work properly... but there are a lot of waffle definitions out there that work with 0.6... so, I would use one of those. Here is another link to a definition written by forum member Taz: http://www.grasshopper3d.com/forum/topics/grillage-fabrication
