(b) Disadvantages

• It takes less time to create, test and modify a wide range of different design ideas.

• There is no physical product model to hold, feel, measure and test.

• It costs less to explore designs compared to creating physical models.

• It is much quicker and requires fewer practical workshop skills than producing physical models.

• Software often needs to operate o powerful computers, which cost more.

• Designers need training and skills to be able to use virtual modelling software correctly.
