Leaders are lines and arrows that show the relationship between two objects. Usually, these two objects are a label and the object it labels.
As a rule, a line leader points to a line, a point leader points to a point and so on.
Leaders get their properties (line type, arrow type, etc) from the Leader tab of the Drawing Settings.
If you draw some leaders, then change the properties in the Leader tab of the Drawing Settings, the properties of the existing leaders will be updated to mach the new settings.
Once drawn, you can right click any leader and change any of its properties. The properties to change on an individual leader are locked in and do not change with the Leader Drawing Settings.
You can add a leader to your drawing anytime by manuall drawing it.
To draw a leader, choose the Draw Leader or Draw Curved Leader command. Follow the command prompts to establish the corresponding end points, angle point and arc.
This command can be repeated. Press 'R' to repeat the command after you choose the Draw Leader command. After you place a text object you'll see the cursor remains a tick(cross) indicating that the Drawing View is ready for another insert point.
Drawn leaders are removed by deleting them.
As a rule, consider adding drawn leaders to the Leaders layer. TPC includes this layer with all of its default drawing templates.
Automatic leaders are ones that get drawn for you via the Traverse Drawing Settings. You can turn these leaders on for point labels and line labels both.
Once an automatic leader has been created, it can be turned off with the Leader Off command and turned back on with the Leader On command.
Just right click the label for which the leader is being drawn and choose the appropriate command.
