ABSTRACT
Computer Aided Drawing (CAD) is now used extensively throughout the engineering industry as a means of communicating drawing data to required standards. Two and three dimensional representations of components can be drawn and modified allowing the sharing of data from designer to customer. CAD data can be shared with CNC machines and Computer Aided Manufacturing (CAM) software, which may then assist in improving productivity, flexibility and quality of the final product. This unit will provide you with an introduction to CAD and to enable you to produce engineering drawings to given industry standards. It will also provide you with the necessary foundation to study CAD at a higher level. When you study this unit, you will be expected to produce engineering and assembly drawings as well as schematic circuit diagrams. You will also be expected to understand and apply the basic procedures of starting-up and closing down a CAD system and the storage, retrieval, modification and printing/plotting of data. The unit builds on some of the work that you carried out in Unit 1: Working Safely and Effectively in Engineering, and Unit 2: Interpreting and Using Engineering Information.
