Technical drawing has existed since ancient times. Complex technical drawings were made in renaissance times, such as the drawings of Leonardo da Vinci. Modern engineering drawing, with its precise conventions of orthographic projection and scale, arose in France at a time when the Industrial Revolution was in its infancy. Engineering drawing, is the most important aspect of mechanical engineering, as it is the fundamental need to develop the design and assembly of a machine. The process of producing engineering drawings is often referred to as technical drawing or drafting. Drawings typically contain multiple views of a component, although additional scratch views may be added of details for further explanation. An engineering drawing follows criteria and conventions to eliminate confusion by 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.

This book provides extensive details about the vast topic of engineering drawing. It deals with the study of applied geometry, threaded fasteners, computer-aided drawing and engineering graphics as a language. It also focuses on manufacturing materials, drawings for numerical control, geometric dimensioning and tolerancing. This book is a valuable compilation of various topics, ranging from the most basic to the most complex ones. The various sub-fields along with technological progress that have future implications are also glanced in this book. For those who have an interest in engineering drawing, this book will prove to be a valuable source of knowledge.
