For this lesson, you'll learn all about 3D CAD. CAD stands for computer-aided design. To make your own objects to 3D print, you'll have to be able to use CAD software. CAD software ranges from free, web-based for beginners (like Tinkercad) to professional-level software suites (like AutoCAD).

We'll begin by learning about the history of CAD, and then we'll explore and use Tinkercad. A link to the web-based software is included in the path. 

To complete this Path and earn an Award, follow the tutorial to design a wrench, and then show it to one of the instructors.
