WJEC Product Design Practice Exam

The correct answer identifies a statement that does not represent an advantage of Computer-Aided Design (CAD). While CAD offers numerous benefits, the assertion that it "always requires expensive equipment" is not accurate in the context of its advantages.

CAD software is designed to run on a range of computer systems, and while high-performance equipment can enhance the experience, particularly for complex designs or rendering tasks, it is not a strict requirement for all users. Many CAD programs are accessible on standard computers, and there are increasingly affordable options available.

In contrast, CAD does allow for easy sharing of designs, which is a significant benefit as it facilitates collaboration among teams and stakeholders. Additionally, CAD aids in saving physical space and storage, as digital files occupy far less room than traditional paper drawings or prototypes. Finally, the level of precision and quality achievable with CAD can lead to a higher quality piece of work, enhancing both design and manufacturing processes. Therefore, the assertion regarding the need for expensive equipment does not accurately reflect the advantages that CAD provides.
