Shifting Points to Connect Lines in Scissor Structures

Hi Everyone,

I am a student (and a total grasshopper newbie). I am wondering if I can draw on your wealth of knowledge to help me out with a problem. I am trying to make cylindrical scissor structures with grasshopper and I am a bit stuck treating points together as a group. If you see the attached pic I have modelled what I want to get in rhino and I am trying to duplicate that process in grasshopper.

Where I am getting stuck is that I can control where the line goes from 1 point to another point, but what I can not control is inner point circle group and how if affects the outer circle points as a group. I want to connect a line from to the outer point circle to the inner point circle by shifting one point to make the scissor structure. Any ideas/tips? Attached is the script and rhino file in case you want to see the original. Thanks!
