CAD

Definition

Computer-Aided Design (CAD) is a technology used for creating, modifying, analyzing, and optimizing designs through computer software. In aerospace engineering, CAD is essential for designing complex components and systems, allowing engineers to visualize and test their ideas in a virtual environment before physical production. This technology significantly improves efficiency and precision in the design process, enabling engineers to innovate and enhance aircraft and spacecraft designs.
