This book provides users with opportunities to learn how to visualize and interpret more complex prints. Ideal for self-paced learning, this workbook-style text continues the emphasis on orthographic projection involving interpretation of lines, views, dimensions, tolerances, notes, and symbols. Advanced areas of inquiry are also addressed, including welding symbols, fasteners, screw threads, and other related topics. Key Features: short, concise units that build upon each other enable users to move quickly from easy to more difficult concepts; double sided drawings in the back of the book provide immediate opportunities for readers interested in machine trades and mechanical engineering to apply new skills; comprehensive coverage, including expanded discussion of current ANSI standards, eliminates the need for additional references. An elementary blueprint reading book is also available.
