About Surface Label Styles
Use the Settings tab of Toolspace to manage surface label styles. You specify which label styles to use when you create surfaces, when using the Add Labels dialog box to add slope and spot elevation labels.
About Surface Watershed Labels
Watershed labels can be considered an attribute of a watershed and not a separate component since they require no placement. Watershed labels are drawn at the watershed centroid.
About Contour Labels
You can create contour labels by specifying line segments that cross contour lines of a surface. Add Single, Multiple, or Multiple at Interval contour labels. Modify the properties of contour label lines to change the label style for major, minor, and user-defined contour labels.
