今天,计算机已普及到了各行各业,人们对其的依赖与日俱增。在工程设计领域,越来越多的设计人员,利用计算机这一强大的工具来减轻设计工作的程度,提高设计水平,从传统的复杂繁重的手工绘图中解放出来。计算机绘图与传统制图相比,具有很大的优势,传统制图技术存在着图纸易损坏、不易保存、不易修改等缺点,给绘图工作带来了很大的不方便,而综合计算机辅助设计和辅助绘图通用软件包,以 AUTOCAD 为例,具有使用方便、界面友 Today, computers have spread to all walks of life, people rely on it growing. In the field of engineering design, more and more designers make use of the powerful tool of computer to reduce the degree of design work, improve the design level, and liberate from the traditional and complicated hand-drawing. Comparing with traditional drawing, computer drawing has great advantages. Traditional drawing techniques have some shortcomings such as easy to damage, difficult to save, easy to modify and so on, which brings great inconvenience to the drawing work. However, the combination of computer aided design and auxiliary Drawing common package to AUTOCAD, for example, with easy-to-use, friendly interface
