In this exercise, you will use label sets to apply several types of labels to an alignment.
You can automatically add labels as you create objects, such as points, alignments, or parcels. Labeling an object automatically is an efficient way to annotate common elements, such as alignment stations or parcel areas, as they are created.
In this exercise, you will specify a label set to apply as you create an alignment from a polyline. Both the newly created alignment and its labels will reside in the current drawing. Next, you will learn how to modify the properties of the label set after the alignment has been created. Finally, you will learn how to apply a label set to an alignment that exists in an externally referenced drawing.
Create a label set for a new alignment
This exercise uses Labels-1a.dwg with the modifications you made in the previous exercise, or you can open Labels-2a.dwg from the tutorials drawings folder.
Polyline in the externally referenced drawing
When you create an object, its Create dialog box typically has style selector lists for both the object and the labels. The style selector lists identify the object styles and label styles that are available in the current drawing for that object type. When you create an alignment, profile, or section, you select a label set, which applies a preset style to each of the various labels types that are in the set. You will examine an example of a label set in the following steps. Notice that there is a _No Labels selection. This selection is an empty label set that does not display any labels along the alignment.
If you do not want to annotate objects that do not use label sets, you can create a label style that has the visibility of all of its components turned off.
The Alignment Label Set dialog box displays information about how the Major Minor and Geometry Points label set is configured. You will use this label set as a basis to create a new label set.
The Information tab displays the label set name, description, and the date when it was created or modified.
The Labels tab specifies the label types that are defined in the label set, as well as the label styles that are used by each type. In this example, you use the label set to apply label styles to the geometry points and major and minor stations of an alignment.
Label sets for profiles and sections are constructed in the same manner, using a similar dialog box.
You can use geometry point label types to label a selection of geometry points using a combination of styles that you specify. In steps 8 and 9, you applied a geometry point label style to the alignment starting station. In the following steps, you will create another instance of the Geometry Points label type that applies a different style to the alignment ending station.
To remove a label type from the label set, select the type and click .
If the EP: 0+243.63 label is adjacent to the intersecting alignment, click Find. Click the alignment. Click OK to acknowledge the warning about alignment properties that are affected by the command.
tab panelWhen the alignment is created, it is green. The green color is controlled by the alignment style that you specified in step 3. Notice that the new red labels are a brighter than the labels that were brought in with the externally referenced objects. The color tones are different so that you can easily identify where the labels reside: bright labels are in the current drawing, and light labels are in the externally referenced drawings.

Modify the label set of an existing alignment
Changes that you make to the alignment label set after the alignment has been created will not be applied to the original label set. To edit the original label set, in Toolspace, on the Settings tab, expand AlignmentLabel StylesLabel Sets. Right-click the appropriate label set. Click Edit.
Alignment with modified label set
In the previous image, the EP: 0+243.63 and PC: 0+158.39 labels are shown on opposite sides of the alignment for clarity. You will learn to flip labels to the opposite side of an alignment in a later exercise.
Add labels to an alignment in a referenced drawing
Because this alignment exists in an externally referenced drawing, the table in the Alignment Labels dialog box is empty. Only labels that are created in the current drawing can be modified in the current drawing. Labels that were created in an externally referenced drawing must be modified in the source drawing.
The Import Label Set button applies a label set that exists in the current drawing.
On the Main Street alignment, labels are displayed at each station at which a new design speed is applied, and at each geometry point. These label objects reside in the current drawing and annotate the alignment in the externally referenced drawing.
