What term describes the use of dedicated computer hardware and software in the design process, such as 3D designs?

• A. Computer-aided drawing
• B. Computer-integrated design (CID)
• C. Computer-aided design (CAD)
• D. Computer-aided manufacturing (CAM)

Answer: (C)

Using dedicated computer hardware and software to help create and refine designs, including 3D models, is called computer-aided design. CAD covers the full design process on a computer, not just drawing. It lets designers create precise 2D drawings and complex 3D models, adjust dimensions quickly, and often run simulations or visualize how a product will look and function before it’s built. This speeds up iteration, reduces errors, and improves collaboration with engineers, manufacturers, and clients. Why the other terms don’t fit as well: computer-aided drawing focuses mainly on digital drawings and is narrower than CAD, which includes 3D modeling and analysis. Computer-integrated design isn’t a standard IB term and isn’t widely used to describe the design process with CAD tools. Computer-aided manufacturing refers to using computers to control production and fabrication, which comes after the design stage, not the design process itself.
