Unroll Ruled Surfaces in Grasshopper
Prompted by a request on the Grasshopper3d.com message board, I set out to make a definition for unrolling ruled surfaces in GH. I’m not the first to attempt it – see the work of Chris Chalmers here: http://biosarch.wordpress.com/2009/09/23/unrolling-surfaces-in-grasshopper/ – but I think my approach may be a bit more streamlined and flexible.
I make no promises about its accuracy, but the result seems to work fairly well, with results comparable to those produced by the “unroll” command in Rhino – however mine tends to produce smaller areas, whereas the Rhino one always seems to tend larger. It will not work on double-curved surfaces! Feedback, real-world fabrication test results, and suggestions for improvement welcome!
