Abstract: The content system of engineering graphics textbook with drawings is proposed. The
contents and methods of textbook adjustment are pointed out, such as the concept of view, the
introduction timing of axonometric projection, the limit and fit, the standard part in detail and
assembly drawings, sorting and perfecting the relation of detail drawings and assembly drawings,
et al. In this paper, the concepts and terms of engineering graphics are expressed exactly, such as
orthogonal projection and view, similarity, formation of rotation body, accumulation and projection,
superposition and level, size datum and main size, third angle method and the description of some
perspective projection terms, to further improve the scientific nature and quality of engineering
graphics course and textbook and the cultivation of high level talents, et al.

Key words: engineering graphics, textbook, course, content system, concepts and terms
