CHAPTER 7CNC Fabrication with Pro, 123D Make, and Cut2D

IN THIS CHAPTER we’ll turn SketchUp models into scaled 2D files that can be fabricated on a computer numerical control (CNC) router. This manufacturing method is common for making crafts, terrain models, and furniture. It’s a more mature technology than 3D printing, and the post-processing work is often easier than cleaning a print. CNC machines operate with computer-aided manufacturing (CAM) software.

Specifically, we’ll slice up the terrain model from Chapter 4 with a CAM program called Autodesk 123D Make and export it into a CAM-appropriate format. We’ll use SketchUp Pro to export the Chapter 3 nameplate into scaled .pdf and .dxf formats and then import the .pdf file into a CAM program ...
