Prototyping with arts and crafts is poor compared to CAD

Prototyping can be done with simple arts-and-crafts materials or through advanced computer-aided design (CAD) software, but the effectiveness of each approach is debated. Critics of arts-and-crafts prototyping argue that while it may be quick and inexpensive, it often lacks precision, scalability, and the ability to translate directly into manufacturing processes. CAD, on the other hand, allows for accurate measurements, digital simulations, and easy revisions, making it far more powerful for professional design and production. However, defenders of low-tech prototyping note that hands-on models can spark creativity and help communicate ideas early in the design process.
