The Theory of Engineering Drawing is a comprehensive guidebook for engineers and architects on the principles and techniques of creating technical drawings. Written by Alphonse Andrew Adler, a renowned engineer and professor of engineering drawing, the book was first published in 1915 and has since become a classic reference in the field.The book covers a wide range of topics, including the use of instruments, the principles of orthographic projection, the construction of geometric solids, and the representation of machine parts and mechanisms. It also provides detailed instructions on how to create different types of drawings, such as sectional views, exploded views, and assembly drawings.Adler's approach to engineering drawing is highly analytical, emphasizing the importance of accuracy, clarity, and consistency in the creation of technical drawings. He provides numerous examples and exercises throughout the book to help readers develop their skills and understanding of the subject.Although the book was written over a century ago, many of its principles and techniques are still relevant today, particularly in the fields of engineering, architecture, and design. It is a valuable resource for anyone seeking to improve their technical drawing skills or gain a deeper understanding of the principles behind the creation of technical drawings.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
