George G. (George Guillaume) André
The Draughtsman's Handbook of Plan and Map Drawing
Including instructions for the preparation of engineering, architectural, and mechanical drawings.
"The Draughtsman's Handbook of Plan and Map Drawing" by George G. André is a technical guide on the art of drafting, written in the late 19th century. The handbook serves as a practical reference for draughtsmen specializing in topographical drawings, engineering, architectural, and mechanical illustrations. The work is designed to offer valuable principles and practices of drawing, while also providing comprehensive instructions for various applications relevant to practitioners in the field. The opening of this handbook outlines its purpose and the intended audience, highlighting the necessity for careful attention to detail in the draughting process. It emphasizes that the work will not be restricted to one type of draughtsman but aims to be broadly useful across various disciplines, including surveying and engineering. The preface discusses the importance of accurate instruments, materials, and methods required for effective drawing, setting the stage for subsequent sections that will explore geodesic techniques, the handling of tools, and the principles of representation through lines and colors.
