摘要： 文中提出了融入图的工程图学内容体系，指出教材调整的内容和方法，如视图概念、
轴测图的引入时机，极限与配合，标准件分别置于零、装图中，理顺、完善零、装图的关系等。
对工程图学某些概念术语进行了探讨，如正投影和视图、类似性、回转体形成、积聚和重影、叠
加和平齐、尺寸基准、主要尺寸和某些透视术语的表述等，以进一步提高工程图学课程和教材的
科学性及质量，励助高水平人才的培养。

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.
