Engineering Drawing - Video course COURSE OUTLINE Engineering drawing is a basic course for all undergraduate Engineering program. Though Engineering drawing is considered as the language of engineers, most of the universities offer this course as a practical course with out any lecture component. This course is therefore introduced to provide the basic understanding of the fundamentals of Engineering Drawing, mainly visualization, graphics theory, standards and conventions of drawing, the tools of drawing and the use of Drawings in engineering applications. The topics covered are based on the syllabus for undergraduate studies in engineering. The lectures would be arranged in a sequence and starts from the b a s i c concepts of geometrical constructions and engineering curves and progress to the principles of projection techniques. Towards the end of the course it is expected that the students would be matured to visualize the engineering component from any drawing sheet. , followed by projection techniques A number of chosen problems will be solved to illustrate the concepts clearly. This video course would be useful for undergraduate engineering students as well as for engineering college teachers. Contents: Introduction & importance of engineering drawing, Manual drawing, drawing instruments and their uses, conventions in drawing, geometrical constructions, scales, curves in engineering practice, principles of projections, projections of points, lines, planes and solids, auxiliary projections, sections of solids:intersections of solids, development of surfaces, axinometric projection and perspective projections.
