Bearing and distance annotations can be linked to the linework,
such that the annotations
will automatically update if the linework is changed. For example, if a
line is moved with the
AutoCAD Move command, the bearing label will update. This link
can be found, and toggled on and off, under Object Linking in
Configure > General Settings. Configure is in the Settings menu.
The link is established between the label and the
line, or polyline, when the label
is created by commands such as Auto Annotate, Line Table or
Bearing_Distance. There are no links for annotation created using
the Points option. To update bearing annotation without using
the dynamic annotation, use the Global
Reannotate command in the Annotate menu. To remove
the links between the annotation and the linework entities, use the
Remove Reactors command, found under File > Drawing Utilities.
