Problems with a planification script

Hey everyone,

I have a problem with a planification script of a waffle structure, and I was hoping someone could help me to fix it!

The script was working just fine with the waffle structure that I had before, when I changed the curves, it started to cause me trouble. Suddenly, there are no snaps on the planification. (I'm Brazilian, so what I mean when I say snaps is the cuts of the structure, when you have the crossing of two elements)

Again, it was working just fine before, and then when I used other curves, it stopped working!

Could someone, please, help me with this, I'm desperate!

PS: For the planification, there are two points, at grasshopper, without values, so you have to make two points at Rhino, and set these values.

Thank you so much!
