The document provides instructions and guidance for students learning to use computer aided design (CAD) software to design a key fob. It outlines the design brief, specifications, learning objectives, and steps to take in the CAD program. The learning objectives are to use basic 2D design tools to create shapes, add color and text, and learn how to prepare a CAD drawing to be laser cut. The document guides students through exercises using tools like lines, circles, grids, colors and text. It also covers annotation, modifying designs to fit on a page at the required size, and changing line colors for laser cutting. The overall goal is for students to use CAD to design 10 different key fob concepts that meet the specifications and can be
