摘要
介绍了图样画法在三维(3D)设计时代的现实需要与国标之间的差异,阐明了CAD/CAM技术的发展与成熟为3D图样创造了物质技术条件,讨论了建立3D图样标准体系的必要性,探讨了3D图样的表达方案,简要分析了3D图样和2D(二维)工程图的关系,提出了以3D图样最终取代2D绘图技术,建立一套系统的3D"图样画法"及相应的国家标准是工程图学发展的迫切目标。
This paper describes the difference between the current needs in the times of 3-dimensional（ 3D） design and the national standard for the representation of drawings, clarifies that the developing and maturing of CAD/CAM technologies have provided a good technology foundation for the 3D drawings, analyzes the necessity of constructing 3D drawings standard system, explores the representation schemes of 3D drawings and discusses the relationship between 3D drawings and 2 - dimensional（2D） drawings. Then it is pointed out that the 3D drawings will replace 2D drawings in the future and is an urgent aim for the development of engineering graphics to create a systemic 3D ＂representation of drawings＂ and its nation standard.
