Grasshopper 1
OpenNest's components run in classic Grasshopper (Rhino 6, 7 and 8). Each component has its own tutorial with a downloadable example — see Nesting (OpenNest2, OpenNest1, OpenNestCollision), Geometry & sheets, and Utilities in the navigation.
The same components also run in Grasshopper 2 (the new Rhino 8 editor) — identical inputs, outputs and behaviour.
