1. The distance of a point from the H plane is the distance of its V projection from the ground line. The distance of a point from the V plane is the distance of its H projection from the ground line.
2. If any two projections of a point are given, the point is fully determined, and the third projection may be found from the above principle.
3. If a line is parallel to either plane of projection, its projection upon the other plane of projection is parallel to the ground line.
4. If a line is parallel to either plane of projection, it will be projected upon that plane in its true length.
5. If two intersecting lines are each parallel to the same plane of projection, the angle between the lines will be projected upon that plane in its true magnitude.
6. If a point lies in a given line, its projections will lie in the corresponding projections of the line.
7. If two lines are parallel in space, their corresponding projections are parallel.
8. The H and V traces of a plane always intersect the ground line at the same point.
9. If any two traces of a plane are given, the plane is fully determined.
10. If a plane is parallel to the ground line, its traces are parallel to the ground line, and conversely.
11. If a plane is perpendicular to either plane of projection, its trace upon the other plane is perpendicular to the ground line, and conversely.
12. If a line lies in a given plane, its H piercing point lies in the H trace of the plane, and its V piercing point lies in the V trace of the plane.

Paperback. Condición: New. Print on Demand. This book is the culmination of the author's study of descriptive geometry, a field of geometry used to represent three-dimensional objects and their relationships. Drawing from the work of foundational thinkers in the field from the very beginning, this book is an ideal starting place for those interested in learning the methodology of descriptive geometry in order to solve a variety of problems. The author covers such concepts as point, line, and plane projections; warped surfaces; and representation of surfaces and space curves. These foundational concepts are thoroughly explained and illustrated before advanced concepts such as surfaces and space curves are covered, allowing the reader to build a strong base of understanding before progressing. Beyond the inclusion of fundamental concepts, this book also includes over 300 exercises and problems with full solutions, offering readers a chance to practice and master the material as they learn it. Overall, this book is a valuable resource for anyone interested in learning descriptive geometry, whether for its historical significance or its practical applications in engineering, design, and architecture. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
