Zip Shape Startkit definition

Hi All,

This semester is the first time my Uni has offered a digital design and fabrication class and we have been asked to choose a project, study the grasshopper definition and then use it to learn how to fabricate something on the CNC, all of which is completely new to everyone at my university.

I have committed to learning Christoph Schindler's Zip Shape Technique and am stuck on the Zip shape startkit script that is provided on the digitalcrafting.dk website.

Is there anyone that can have a look at it for me and maybe explain to me a little about how to resolve it?

The focus on the class isn't so much on the grasshopper side (it's just a very basic introduction) but on the process of rhino/grasshopper to CNC fabrication.

Thankyou for your time
