Features: This book is compiled based on the current research direction and development trends of graphic education in China's universities, combined with the "Basic Requirements for Teaching of Descriptive Geometry and Engineering Drawing" promulgated by the former State Education Commission, as well as the authors' many years of teaching experience. The main contents include: an overview of projection methods, the projection of points, lines, and planes, the relative positions of lines and planes, planes and planes, projection transformation, commonly used curves and surfaces in engineering, plane solids, intersection lines, intersection curves, isometric projection, shadows in orthographic projection, perspective projection, and contour projection. Rotation method is another method of projection transformation. Its characteristic is that the projection plane remains unchanged, while the spatial geometric elements are rotated around a certain axis to a special position relative to the projection plane, so that their true lengths, true shapes, or the real sizes of their angles and distances can be reflected.
