What is 3D CAD design?

3D CAD (Computer-Aided Design) refers to the use of computer software to create, modify, analyze, and document a 3D representation of a physical object. It is widely used in various industries like manufacturing, architecture, engineering, and construction to design products, buildings, and infrastructure. It allows designers and engineers to visualize, simulate, and optimize their designs before physical prototypes are built, reducing costs and improving efficiency. Common uses include creating detailed models for manufacturing, generating blueprints, performing simulations to test performance, and producing photorealistic renderings for marketing purposes.
