Label curve styles define the content and display of annotation labels. When you create, edit, or copy label styles, you use Style Manager. Style Manager provides a central location where you can view and work with label styles from multiple drawings and templates.
You can specify the text style, position of text on the curve, the information displayed in the label, and how the label is displayed in your drawing. When you change a label style, the labels in the current drawing that were created with that style change.
