What are choosing modelling materials?Show answer
Early models use cheap, easy-to-work materials such as card, foam board, modelling foam and clay, because they are quick to cut, shape and change. This suits the early aim of trying many versions fast, and it encourages experimentation, because nobody minds altering or discarding a card model. As the design firms up, prototypes move to materials closer to the final ones (woods, plastics, metals) to test real function and strength.
What is using models to gather evidence?Show answer
A model is only useful if it informs the design. The designer tests the model (does the phone fit the slot? does the handle feel comfortable? does the stand tip?), records what is found, and uses the evidence to refine the design.
What is not testing the model?Show answer
A model that is made but never tested gathers no evidence and does not advance the design.
