Which term describes the creation of physical or digital prototypes to test size, shape, function or assembly before final manufacture?

• A. CAD (Computer-Aided Design)
• B. Modelling
• C. Evaluation
• D. Sustainability

Answer: (B)

Creating prototypes to test size, shape, function or assembly before final manufacture is modelling. This involves making physical or digital representations to check how parts fit, how a product will work, and whether dimensions are correct, so problems can be found and fixed before committing to production. CAD is the software used to design those models, but modelling is about the actual creation and testing of prototypes. Evaluation is about judging results after testing, and sustainability focuses on environmental impact and life-cycle considerations, not the act of prototyping.
