A computer-aided design is the generation, creation, development and analysis of a design or system using computer software. The use of CAD to simulate the conditions in which a product will be used allows the designer to gain valuable data at low cost. For example, simulating the flow of air across a car exterior negates the need for a car and wind tunnel

• Types of CAD software

• Surface and solid models

• Data modelling including statistical modelling

• Virtual prototyping

• Bottom-up and top-down modelling

• Digital humans: motion capture, haptic technology, virtual reality (VR), and animation

• Finite element analysis (FEA)

• Advantages and disadvantages of using computer-aided modelling

• How data models structure data through database models

• Design of information systems to enable the exchange data

• How haptic technology, motion capture, VR and animation can be used to simulate design scenarios and contexts

• Comparison of FEA with testing physical models

• Use of FEA systems when designing and developing products

As technologies improve and the software becomes more powerful, so do the opportunities for designers to create new and exciting products, services and systems. Greater freedom in customization and personalization of products has a significant impact on the end user. The ability to virtually prototype, visualize and share designs enhances the whole design cycle from data analysis through to final designs.
