To Work With Alignment Station Labels

Station labels display reference information about specific points along the length of an alignment. Autodesk Civil 3D supports the following alignment station label types:

• Major Stations
• Minor Stations
• Geometry Points
• Profile Geometry Points
• Station Equations
• Design Speeds
• Superelevation Critical Points
• Cant Critical Points

When you create an alignment, you select a label set, which is a predefined collection of label types with associated styles. You can modify the station labels in an existing alignment, and then optionally save the changes as a label set.

After an alignment has been created, you can change the type and style of the station labels. You can save a collection of alignment station label types and styles as a label set, which can be applied to other alignments.

If you label an alignment created through an xref, the labels you add exist in the current drawing. If you detach the xref, labels created in the current drawing will be lost.

To change the display of the station character

Use the Station Character setting to change the display of the character in station labels. The following station character formats are available:

• 10+50.00
• 10-50.00
• 10_50.00
• 1050.00
• 10/50.00
• 10C50.00
• 10K50.00

1. In Toolspace, on the Settings tab, right-click a station label type. Click either Edit or New.
2. In the Label Style Composer, click the Layout tab.
3. Under Text, click in the ContentsValue column.
4. In the Text Component Editor, in the preview pane, select the station value property formula.
5. In the Properties list, select Station Value.
6. Click the Station CharacterValue column. Select the desired character from the list.
7. Specify other modifiers as necessary.
8. Click to insert the property into the Text Component Editor window.
9. Click OK.

To edit alignment station labels

1. Click Annotate tabLabels & Tables panelAdd Labels menuAlignmentAdd/Edit Station Labels.
2. Select an alignment in the drawing to open the Alignment Labels dialog box.
3. In the Alignment Labels dialog box, do any of the following procedures, and then click OK.

To add a station label type to the alignment

1. In the Type list, select the type of label that you want to add.
   Note: To add minor station labels, you must have at least one major station label type added to the label set.
2. In the Style list, select a style for the label type.
3. Click Add.
4. If you select either the Geometry Points, Profile Geometry Points, Superelevation Critical Points, or Cant Critical Points label type, select the specific points to label.

To delete a station label type from the alignment

To delete a label, select the label type and click . You cannot delete a major station if it has a minor station.

To change the parameters of an existing station label type

1. In the Style column, either click the icon to change the style or accept the label style selection.
2. In the Increment column, either enter a value to determine the increment distance between major station labels, or accept the default.
3. In the Start Station column, either clear the check box and enter a new starting station value or accept the default.
4. In the End Station column, either clear the check box and enter a new end station value or accept the default.
   Note: The default start and end stations for each label type are the beginning and end of the alignment. To change either the start station or end station, clear the check box, and enter new start station and end station values.
5. In the Geometry Points To Label column, click to update the points to label.
   Note: The Geometry Points To Label column is only available for the Geometry Points, Profile Geometry Points, Superelevation Critical Points, and Cant Critical Points label types.
