Excerpt from Practical Descriptive Geometry The first edition of this book, published in 1912, represented the author's views on the presentation of Descriptive Geometry, so as to arouse the student's interest in the subject without sacrificing rigorous training in the principles. In three years the text has been used in many schools, and the present, second edition, aims to embody the suggestions of many leading teachers of the subject, who have, at the request of the author and publishers, expressed their views as to this development. The main idea of the first edition, that of "practicality," has been adhered to and amplified. The most important changes are: 1. The division into more chapters. 2. A more logical sequence for certain portions of the text. 3. The notation of points and planes. 4. Graphic layouts for exercises. 5. More exercises of a practical nature, embracing more lines of engineering endeavor. 6. A number of new solutions, utilizing auxiliary planes more frequently. 7. A better system of perspective drawing. 8. A chapter on the intersections of plane solids. Although yielding to the request of several teachers for the inclusion of graphic layouts of exercises, the author still believes that dimensioned layouts are of great value despite the amount of time expended on the layout itself. With both of these, however, in practically unlimited quantity, the instructor may decide the question for himself. The layouts of both kinds have been made so flexible by interchanging and substituting data, that the number of variations is almost incalculable. This removes the objection, expressed by some teachers, to a definite and limited number of exercises, the solutions of which are sometimes preserved by student organizations. No such collection of solutions will benefit future classes, as the exercises can be made entirely different each succeeding year.
