Foundations of Computer-Aided Design (CAD)

Computer-Aided Design (CAD) is the backbone of modern engineering, architecture, and product design. Understanding how to translate a creative concept into a precise digital model is an essential skill for any aspiring creator. This written course guides you through the fundamental concepts of CAD from the ground up. You will learn how to think like a designer, understand coordinate systems, and grasp the core mechanics of both 2D sketching and 3D parametric modeling. Learn the fundamental terminology, history, and applications of CAD across various industries. Grasp the differences between 2D drafting, 3D wireframe, surface, and solid modeling. Master core geometric constraints, dimensioning rules, and coordinate systems. Learn the principles of parametric modeling and feature-based design histories. Explore modern collaborative cloud CAD workflows and data management practices. Prepare design files for manufacturing processes like 3D printing and CNC machining. The course begins with essential terminology and the math behind digital design before progressing to sketching principles, feature creation, and assembly basics. You will solidify your knowledge through detailed written explanations, step-by-step structural analysis, and conceptual exercises. This course is designed entirely for beginners with no prior engineering or drafting experience. Start reading today to build a strong foundation in digital design.
