Graphics and design

3.2. Comprehension tasks

3.2.1. Mark the following statements as True or False:

1. CAD is used to design and create only 2D virtual models of goods and products. Is it true?
2. The benefits of virtual simulations are limited. Is it true?
3. New developments in CAD applications and technologies are regularly presented at industry conferences and in peer-reviewed journals. Is it true?
4. It is possible today to run most CAD software on typical PCs. Is it true?
5. In the future we will be able to create a physical prototype – solving a drawback of virtual product development. Is it true?

3.2.2. Using the information in the article, complete these statements

1. The benefits of virtual simulations are obvious because:
   • using computer-aided manufacturing software, engineers can simulate and test designs before parts are actually produced
   • there is the advantage that conceptual designs can be modified instantly as the tests progress
   • testing can be time-consuming and expensive
2. New developments in CAD applications and technologies are regularly presented
   • on special Web sites
   • at industry conferences such as ICCAD, in peer-reviewed journals such as Computer- Aided Design and Applications
   • in periodicals
3. In the future we can expect further advances in 3D software packages, allowing
   • large and small enterprises to use CAD applications
   • most CAD software to be run on typical desktop PCs
   • users to create a physical prototype – solving an inherit drawback of virtual product development
