This module introduces the fundamental principles and application of computer aided drawing and design. It introduces the learner to procedures and techniques that enable the production of CAD drawings. It begins with basic commands (assumes no prior knowledge) and proceeds to the production of more complex drawings of solid components using Isometric, surface and solid model methods.
