Except for the associativity relation between the leader and annotation, the leader and its annotation are entirely separate objects in your drawing. Editing of the leader does not affect the annotation, and editing of the annotation does not affect the leader.
除了引线和注释之间的关联性关系以外，引线与其注释在图形中是完全独立的两种对象。编辑引线不会影响注释，编辑注释也不会影响引线。
Although text annotation is created using the DIMCLRT, DIMTXT, and DIMTXSTY system variables to define its color, height, and style, it cannot be changed by these system variables because it is not a true dimension object. Text annotation must be edited the same way as any other MText object.
虽然可以使用 DIMCLRT、DIMTXT 和 DIMTXSTY 系统变量通过定义文字注释的颜色、高度和样式来创建文字注释，但是，不能通过这些系统变量对其进行更改，因为文字注释不是真正的标注对象。文字注释的编辑方式必须与任何其他 MText 对象的编辑方式相同。
Use the Evaluate method to evaluate the relation of the leader to its associated annotation. This method will update the leader geometry if necessary.
使用 Evaluate 方法来评估引线及其关联注释的关系。这个方法在需要时会更新引线。
