Designing a keychain in a Computer-Aided Design (CAD) class involves creating a 3D model from scratch using various software tools and techniques. The first step is to decide on the overall shape and functionality of the keychain, considering factors such as size, material, and weight. To start, students typically use a CAD program like Fusion 360 or SolidWorks to create a basic shape for their keychain. This can involve drawing profiles, extruding shapes, and combining them into a single model. The goal is to achieve a precise and smooth design that will serve as the foundation for further details and features. Next, students add texture, patterns, and other visual elements to give their keychain some personality. This might include adding intricate designs, engraving text or logos, or even creating a custom color scheme using various materials and finishes. The possibilities are endless, allowing students to express their creativity and imagination. In addition to aesthetics, the design process also involves considering the keychain's functionality. Students must think about how it will be used, where it will be worn, and what kind of load it will need to withstand. This might involve adding reinforced structures, securing mechanisms, or even integrating other features like a bottle opener or flashlight. Throughout the design process, students receive feedback from their instructors and peers, helping them refine their ideas and achieve their desired outcome. The end result is a unique and functional keychain that showcases their skills and creativity in CAD design.
