What does CAD stand for in engineering design?

The term CAD stands for Computer-Aided Design. This concept refers to the use of computer software to facilitate and enhance the engineering and design process. CAD allows engineers and designers to create precise drawings and models, enabling them to visualize objects in 2D or 3D formats. The use of CAD software improves productivity, accuracy, and efficiency, allowing for rapid modifications and design iterations. By streamlining the design process, CAD significantly contributes to the development of complex products and systems, making it an essential tool in modern engineering practices.

While the other choices might seem plausible, they do not correctly reflect the established terminology or the functionality of CAD in the context of engineering design. For instance, "Computer-Assisted Design" is not used commonly, nor does it encapsulate the full scope of CAD as tools and processes involved in design. Similarly, "Computer-Aided Development" and "Computer-Adjusted Design" lack the industry recognition and relevance associated with CAD's role as a comprehensive tool for aiding design processes.
