(b) Disadvantages of card modelling

• Models are not made of the production materials.

• Materials are inexpensive and available in a range of types and colours.

• Models are often not functional so it is not possible to test them.

• Models are relatively quick to produce.

• This method is only useful for the relatively simple models, as not all details shown.

• It requires only simple tools and processes.
