Mechanical Drawing

This book is divided into twelve parts, including: basic knowledge and skills of drawing, basic orthographic projection, three-dimensional projection, assembly, axonometric drawing, common expression methods of machine parts, standard parts and commonly used parts, parts drawings, assembly drawings, and computer drawings. Focusing on cultivating students' three abilities: freehand drawing, ruler and compass drawing, and computer drawing, the latest national standards for "Technical Drawing" and "Mechanical Drawing" are adopted. There are reflection questions at the end of each chapter, and appendices and references at the end of the text. The "Mechanical Drawing Exercises Collection" accompanying the book was also published at the same time. This textbook can be used as a drawing course material for mechanical and near-mechanical majors in higher vocational colleges, as well as related course materials for adult higher education and other levels, and as a reference book for relevant engineering and technical personnel.
