Digital Contour Gauge

A contour gauge is a useful tool for extracting a flat, two dimensional profile from a three dimensional object. What would be even more useful, is if the tool could input into a computer, for use in CAD modeling. This is what I've attempted to do with this prototype tool. It uses Firefly for Rhino and Grasshopper to collect data from the arduino-based hardware. Follow these instructions to make your own, make changes, developments, and contribute to this project!
