This book teaches aspiring students the fundamentals of technical drawing with rigorous attention to detail with conventional and modern techniques. The first chapter introduces the notion of auxiliary views, which are obtained when the lines of sight are not parallel to the major projection planes (frontal, horizontal or profile). The following chapter is pictorial drawing, which provides a 3D depiction to aid in comprehending the contour of an object or deciphering a drawing. The working drawing system, which is used throughout the construction or manufacture of a product, is thoroughly detailed in Chapter 3. The final three chapters covered modern engineering drawing using the AutoCAD application. AutoCAD is the use of computer technologies to facilitate the design, modification and optimisation of 2D, and 3D design. Students can also test their understanding by tackling the exercises provided in this book.
