A TEXT BOOK OF ENGINEERING GRAPHICS  (English, Paperback, Dr. C. M. Anand Partheeban)

Engineering drawing, most commonly referred to as engineering graphics, is the art of manipulation of designs of a variety of components, especially those related to engineering. It primarily consists of sketching the actual component, for example a machine, with its exact dimensions. The scale of dimensions is suitably adjusted so as to properly fit within the contours of the drawing sheet. In some cases, depending in the discipline, there are areas of particular focus, such as in the case of Structural Engineering. Another consideration is in regards to the units of measure used; these could be not only Metric or Imperial, but also the way these are noted is relevant, because it will also reflect the precision of a dimension. Hence, engineering drawing plays a vital role both in manufacture and design, as it not only explains the string of arrangement in a machine, but also tells us about the method to be employed to manufacture the individual blocks. An engineering drawing not only helps convey ideas and convert concepts into reality, an engineering drawing follows criteria and conventions to eliminate confusion by the the standardization of nomenclature and practices, as a way to clearly relay the information to the individual who understands it when it is read, and very importantly, it indicates or hints how something is going to be manufactured.
