| The aim of the course |
A new system or structure must exist in the mind of an engineer or designer before it can become a reality. Design process is an exciting and challenging effort, during which the engineer uses graphic language as means to create, record, analyze, and communicate design concepts or ideas.
The engineer or designer must understand how to read and write in the graphic language. Engineers and designers must be able to create idea sketches, , size parts, specify materials and production methods, make design layouts, and supervise the preparation of drawings and specifications that will control the numerous details of product manufacture, assembly and maintenance. To perform or supervise these many tasks, engineers communicate to others through freehand sketches or drawings created using Computer Aided Design or Computer Aided Drafting (CAD). Preliminary sketches are followed by more exact sketches and the drawings as the idea is developed more fully. CAD can help you create drawings, but it takes skill to know which drawings and what level of detail is required at each design stage. While CAD has replaced traditional drafting tools for many design teams, the basic concepts of graphic communication remain the same.
