Digital or virtual prototyping allows us to interact with a digital model and simulate and predict its functional behaviour, just as we would interact with objects and test them in the physical world. The modelling capability and processing power of the computer allow unprecedented scope for creativity. "What if" is the key to completely new insights. Digital prototyping is the gateway to a whole range of new products and processes defined by pure logic.	New product designs can be evaluated for form, fit and function to improve styling, performance, ergonomics, manufacture and maintenance characteristics - to make sure they work as intended before something is physically built. Visualisation, simulation and prototyping are equally helpful for modelling financial data and economic processes. They can support difficult decision-making processes and consensus building. They can provide critical input in urban planning and environmental interaction.	Digital prototyping is particularly useful if you want to: review styling and industrial design   develop and review mechanical design   simulate the functionality of a new product   develop factory layouts and simulate robotic motion
