Asin: B03B1ZF8W Descriptive Geometry and Engineering Drawing is compiled according to the Basic Teaching Requirements of Engineering Drawing for Engineering Undergraduates in Colleges and Universities approved by the State Education Commission 1995 and the latest national standards. Descriptive geometry and engineering drawing are divided into ten chapters, plus an appendix. The main contents include: basic knowledge of drawing, basic knowledge of projection, three-dimensional projection, assembly, axonometric drawing, expression method of machine shape, part drawing, fasteners and common parts, assembly drawing and three-dimensional surface development.

Descriptive geometry and engineering drawing can be selected by related majors in colleges, higher vocational colleges and other schools, and can also be used as a reference for related engineers and technicians. foreword
