CAD and 3D Modeling for Product Design and Prototyping

Bringing a creative product design to life requires more than just artistic vision; it demands a solid understanding of modern Computer-Aided Design (CAD) systems. This text-based course guides you through the foundational principles of 3D modeling, parametric design, and manufacturing preparation. By reading and working through the practical design scenarios, you will learn how to translate raw concepts into precise digital models, generate clean technical documentation, and optimize your designs for modern manufacturing and prototyping methods. What you'll learn: - Understand core CAD terminology, interface structures, and the fundamentals of parametric design. - Create precise 3D models of design objects using standard geometric constraints and features. - Apply modern design-for-manufacturing (DFM) principles to optimize models for 3D printing and production. - Generate professional technical drawings and documentation to clearly communicate design specifications. - Explore topology optimization and material selection basics for sustainable product design. - Prepare digital prototypes and export clean files suitable for rapid prototyping systems. The course begins with essential CAD concepts and basic sketching techniques before moving into advanced parametric features, structural modeling, and drafting. You will then study real-world manufacturing constraints to ensure your digital designs are ready for physical production. This course is designed for aspiring product designers, makers, and hobbyists with no prior CAD or engineering experience.
