This book elucidates the mechanical application of Descriptive Geometry, a discipline combining principles of mathematics and art, to achieve a perspective drawing. The author divides the subject into two methods: Method by Use of the Plan and Method by Scale. In the former, rays are orthographically projected to demonstrate perspective; the latter uses a scale for greater speed and accuracy in locating vital points. This book is written with the student in mind and is an invaluable resource for draftsmen, artists, and freehand draftsmen. While assuming the student has some familiarity with Descriptive Geometry, the author has chosen subjects to illustrate important principles and their general interest, including solids such as pyramids, cubes, cylinders, and their shadows. The depth of perspective and the author's approach to presenting a variety of positions for each subject make this book a valuable resource.
