基于AutoCAD的尺寸公差标注方法研究

Research on Methods of Dimensioning the Tolerance Based on AutoCAD

研究了在AutoCAD中标注尺寸公差的四种方法,分析比较了各种标注方法的特点、适用条件及存在不足;提出了不同方式的公差采用何种标注方法最方便、快捷;并用简便的方法解决了用"Mtext"标注具有"零"偏差时易出现"零"偏差与上或下偏差的小数点前的个位数不对齐的问题.

Researched four methods of dimensioning the tolerance in AutoCAD, Analyzed and compared the characteristics of the various dimension methods, application conditions and the existence insufficiency. Put forward different ways of tolerance uses what dimension method to be most convenient, quickly; And solved the problem occurs that the first zero of the upper and lower deviation can＇t align used the ＂Mtext＂ dimensioning the tolerance had ＂zero＂ deviation by the simple method.
