Cutting Topographical Maps on the CNC Router

This blog post is primarily for my own notes. It's a work in progress. As my project progresses and I encounter more challenges, I will write about them here.


  1. Import map from Google Earth plugin on SketchUp
  2. Geo-location → Add location
  3. Select show terrain
  4. Export from sketchup as a .3ds
  5. Import on Rhino as “Component / 3D Model”
  6. Set size
  7. Set Toolpath
  8. Cut “3D Rough Toolpath” first
  9. Cut “3D Finishing Toolpath”
