In this exercise, you will select labels and change their location in the drawing.
Your drawing currently contains many labels, some of which overlap one another. You will move them in the following steps.
Some label types, such as alignment station and geometry point labels, are part of a label type group that shares properties. When you click one label in the group, the entire group is selected. Properties for the group are controlled using the AutoCAD Properties palette, which is available when you select the group, right-click, and click Label Properties. You can select the group and then change the properties of all labels in the group simultaneously. Alternatively, you can use Ctrl+click to select and change label properties individually.
Other label types, such as segment labels, are not part of a group. Each of these labels is treated as an individual object.
Labels are distinct objects that are independent of the parent object that they annotate. Labels are dynamically linked to their parent object and automatically update when the parent object changes. However, labels reside on a separate layer and are not selected when you select the parent object.
If a label resides in an externally referenced drawing, the label cannot be edited in the current drawing.
Point, parcel area, corridor, and surface watershed labels are not label objects. They are sub-entities of a parent object and their properties are managed in the Label Properties dialog box.
This exercise continues from Exercise 2: Manually Labeling an Object.
Select labels in a drawing
This exercise uses Labels-2a.dwg with the modifications you made in the previous exercise, or you can open Labels-2b.dwg from the tutorials drawings folder.
Notice that the alignment is highlighted, and grips appear along the alignment. The alignment labels, however, are not highlighted.
In previous versions of Autodesk Civil 3D, labels were sub-entities of their parent object. Now, most Autodesk Civil 3D labels are independent objects that reside on their own layer. Although they are independent objects, labels are dynamically linked to their parent object and automatically update to reflect changes in the parent object.
Notice that all other station labels along the alignment are now highlighted.
Notice that while that curve label is selected, the other curve labels are not.
There are two distinct label object types:
Move labels in the drawing
Label dragged with the label location grip
A leader line is created from the label to the alignment.
Label moved with label anchor grip
A leader line is created from the label to the alignment.
Notice that the label displays without a border. The border is hidden because the dragged state of the label style specified a different format for when the label is dragged to a new location. You will learn about label style settings in the Working with Label Styles tutorials.
Alignment end point label displayed in dragged state
You can reset a selected label by clicking the circle grip.
Alignment with labels moved to improve readability
Select labels in an Xref
Notice that both the Main Street and East Street alignments and their station labels are selected. The labels were selected because the labels were created in the externally referenced drawing in which the alignments reside. When an object has been created through an Xref, you can edit its labels only in the source drawing.
