A Very Good copy. A guide to accurately depicting shades and shadows in architectural drawings. Intended for use by beginning architecture students. Authored by Richard S. Buck, an architecture professor, who was assisted by fellow architecture professors Wilbert C. Ronan and Galen F. Oman. Edited by Thomas E. French, Professor of Engineering Drawing. Excerpt from the Preface: "Every student who proposes to take up architectural design must first master the principles of shades and shadow, for that branch of graphics gives the readiest means of presenting the solidity of a building on a single-plane diagram. In order to fill the need of a text addressed explicitly to the beginning architectural students, we have assembled those graphical problems which constantly arise in architectural work, with the solutions which will actually be used on presentation drawings. The latter requirement strictly limits the choice of methods. We have chosen only those based on the simplest procedures of descriptive geometry. All are designed to use the least possible number of construction lines; accurate curves are sought by the use of guide tangents and through knowledge of the character of the line rather than by multiplying plotted points. Auxiliary free-hand curves are reduced to a minimum. In the matter of arrangement, after the two introductory chapters, each chapter deals with one of the basic methods. Every general discussion is followed by a group of problems which employ the method. The problems in the introductory chapters are indicated by means of letters. In the rest of the text the problems are numbered." The following are some of the subjects addressed in this book: "Representing Solid Blocks on Paper," "Why We Plot Shadows," "The Views of a Point," "Direct Figures," "Oblique Plane Surfaces," "Moldings," "Assumptions of Shades and Shadows," "Definitions of Shade and Shadows," "The Light and Its Path, the Ray, Shadows of Points," "Planes of Rays, Shadows of Lines and Shade Lines, "Third Assumption: Parallel Rays," "Fourth Assumption: The Conventional Angle. The Conventional Ray in Space," "The Method of Oblique Projections. "Direct Figures in Elevations and Plans," "Direct Lines and Planes," "Simple Architectural Forms," "Shadows on Thwart Surfaces," "Application of the Twice Rule," "Oblique Straight Surfaces," "The Method of Parallel Shadows," "The Method of Guide Tangents," "Shade Lines Found from Shadows," "The Method of Tangent Surfaces," "The Method of Auxiliary Views," "The Method of Summation," "Axes of Symmetry," "The Method of Auxiliary Shadows," "The Method of Shadows on Traces," "Illustrative Examples," "Block Skyscrapers," "Polygonal Building with Flagpoles," "Shadows of an Arcaded Portico," "A Tuscan Column Rendered," "Shades and Shadows of a Block Ionic Capital," and "Roman Vases (After Piranesi).".
