In chapter 2 lesson 5, we finish the bottom half of our Arduino enclosure by adding mounting pads and creating clearance for the USB and charge ports. You’ll learn how to use projection and offset tools to reference one body against another, ensuring that features like holes and ports are aligned correctly. We’ll also cover how to manage extrusions with “to object” references for flexible designs that update automatically when parts change. By the end, you’ll have a fully prepared bottom box, complete with standoffs and cutouts, ready to pair with a lid in the next lesson.

What You’ll Learn:

• How to reference bodies in CAD to ensure proper clearance and fit
• Using the Project tool to transfer geometry from one body to another
• Creating mounting pads with “to object” extrusion for parametric flexibility
• Adding USB and charge port cutouts with offset dimensions for manufacturability
• Best practices for preventing mistakes when cutting across multiple bodies
• Finalizing the bottom enclosure of your design before building the lid
