To Specify the Default Style Settings for Label Types
In Toolspace, on the Settings tab, right-click a label style type and click Edit Label Style Defaults.
Note: Label style types are the lowest-level collection within the Label Styles collection. For example, under Alignment, expand Station to display the label style types Major Station, Minor Station, Geometry Point, and so on.
In the Edit Label Style Defaults <Style Type> dialog box, define defaults for all label styles belonging to that label type collection by changing the property settings in the Value column.
When you change a value at the current level, the check box is selected in the Override column.
Optionally, lock any setting by clicking to change it to .
