This document discusses the hardware and computer configuration requirements for CAD/CAM applications. It notes that a typical CAD system includes a graphics terminal, input devices like a mouse, output devices like plotters, a central processing unit, and secondary storage. It also lists benefits of CAD over conventional design like improved productivity, shorter lead times, better designs, and easier incorporation of customer feedback. The next class topic will cover input and output computer peripherals used for CAD.

4. How to get autocad?
• Autodesk (the company behind AutoCAD)
tries to engage students to learn about 3D. In
fact, the student version of AutoCAD has no
differences compared to the professional
version, in terms of features and functionality.
