Following a unique approach, this book utilizes freehand sketching techniquesto present the fundamentals of engineering graphics as well as to develop visualization skills. Readers will be guided through critical concepts ranging from projection theory and pictorial sketching to parametric solid modeling and product dissection. They'll find planar projection theory serves as the basis for discussion of the various types of freehand sketching techniques. INDICE: Chapter 1 Engineering Design. Introduction.
