关于共基准尺寸简化注法的探讨

Discussion about the Simplified Annotation of Dimensions from a Common Base Line

从实际应用和计算机绘图的需要出发,对共基准尺寸简化注法的统一性、合理性以及简化的综合效果进行了探讨。笔者认为在实际应用中,过多的简化方式极易引起认识、理解上的混乱;而在用计算机绘制工程图样时,采用标准规定的简化注法,反而使制图工作复杂化,简化的综合效果不佳。同时,根据共基准尺寸的组成特点,对共基准尺寸的简化注法提出了具体修订建议。

From the practical application and the needs for computer graphics, this article makes a discussion of the oneness, rationality of simplified annotation of dimensions from a common base line and simplified synthesized effect. The author thinks overmany simplified ways will easily cause confusion of understanding and comprehension in practical application. While making engineering drawing by computer, standard simplified annotation instead will complicate the drawing work and influence the synthesized effect of simplification and specific suggestions is put forward, based on feature of dimensions from a common base line.
