Computer graphics has had a dramatic impact on the design process. Today, most mechanical and electronic designs are executed entirely on computer. Increasingly, architectural and product designs are also migrating to the computer. Automated tools are also available that verify tolerances and design constraints directly from CAD designs. CAD designs also play a key role in a wide range of processes from the design of tooling fixtures to manufacturing.

CAD has had the follow impact on computer graphics.

1. Drives the high-end of the HW market
2. Integration of computing and display resources
3. Reduced design cycles (faster systems sooner)
