A named dimension style is a group of settings that determines the appearance of a dimension. Using named dimension styles, you can establish and enforce drafting standards for the dimensions in a drawing.
命名标注样式是一组用于确定标注外观的设置。使用命名标注样式，可以建立和实施图形的绘图标准。
All dimensions are created using the active dimension style. If you do not define or apply a style before creating dimensions, AutoCAD applies the default style, STANDARD. To set the active dimension style, use the Dimstyle property of the current database.
所有标注都使用活动标注样式来创建。如果在创建标注之前未定义或应用样式，则 AutoCAD 将应用默认样式 STANDARD。要设置活动标注样式，请使用当前 Database 的Dimstyle 属性。
To set up a dimension style, you begin by naming and saving a style. The new style is based on the current style and includes all the settings that define the parts of the dimensions, the positioning of text, and the appearance of annotation. Annotation in this case means primary and alternate units, tolerances, and text.
要设置一个标注样式，请从命名和保存样式开始。新样式以当前样式为基础，并包括对标注组成部分的布局、文字位置以及注释外观的所有后续更改。这里的注释指主单位、换算单位、公差和文字。
