”  In this Grasshopper video tutorial we will be creating different patterns of Iso-curves that have the potential to be used as toolpaths for CNC milling machines. In this first version of the exercise we’ll create a “parallel cut” pattern on the surface by extracting parameters incrementally along one edge. We will then modify the “parallel cut” pattern to be affected as the surface climbs / descends in the Z value. This video encourages designers and students to design not only the parts, but also the fabrication techniques. ”

Topics Covered:

• Extracting BREP Wireframe / Edge Curves
• Dividing Curves
• Finding the Closest Point on a surface
• Evaluating a surface at a parameter
• Creating / Translating Iso-Curves
