Hi, this is really cool stuff. I was wondering if you could send me the definition as an reference, since we are working on form finding in studio and I am a starter in grasshopper and  don't know how to make the cutting edge lifting up in GH as it is in physical model. If I may, this is my email: srong@design.upenn.edu. Thanks in advance for your time and consideration. 

Great ... could you share the definition to understand the geometry of the cuts? hug
