At its core, CAD design is the process of creating 2D and 3D models of parts, products, or entire systems on your computer. Think of it as digital sketching – but with precision, power, and the ability to simulate real-world behaviors like stress, temperature, and motion. 

Engineers and designers use CAD tools to go from idea to prototype, to production — all before the first part is even built. Learning CAD gives you the superpower to create, iterate, and innovate at scale.
