How to create leaders to indicate details or callouts in AutoCAD.

2. Basic Parts of a Leader Object
A leader object is a line or a spline with an arrowhead at one end and a multiline text object or block at the other. (See below examples)

3. Types of Leaders LEADER MLEADER QLEADER (LE)
Creates a line that connects annotation to a feature.
MLEADER
Creates a multileader object.
QLEADER (LE)
Creates a leader and leader annotation.

4. Leader Addition Choices
NONE
This multileader object contains a leader only.
BLOCK
Several default blocks are available such as circle, slot, and triangle. The default block options contain attributes. You can also specify your own
block. You are prompted for values when you create the multileader.
MTEXT
This is the default
multileader type and consists of mtext objects.

5. Follow the Leader
A leader is designed to come into your drawing as one solid object, similar to a block. This means that while you can use grips to stretch different sections, it is all one piece and will move together. When associative dimensioning is turned on (DIMASSOC system variable), the leader arrowhead can be associated with a location on an object using an object snap. If the object is relocated, the arrowhead remains attached to the object and the leader line stretches, but the multiline text remains in place

6. Getting Leaders in ribbons
These commands are found on the Leader panel in the Annotate tab.
Icon
Command
Description
Multileader
Creates a single multileader object.
Add Leader
Adds leader lines to existing multileader objects.
Remove
Leader
Removes leader lines from existing multileader objects
Align
Multileaders
Aligns multileaders horizontally or vertically in the drawing.

7. Modify Leaders Using Grips
You can make many leader edits directly using multi- functional grips. You can add and remove leaders, add and remove vertices, lengthen or move the landing line, or move the leader text.
■ From the Landing grip, you can choose:
■ Stretch to move the leader landing.
■ Lengthen Landing to extend the Landing line.
■ Add Leader to add one or more leader lines.
■ From a leader endpoint grip, you can choose:
■ Stretch to move the leader endpoint.
■ Add Vertex to add a vertex to the leader line.
■ Remove Leader to delete the selected leader line.
■ From a leader vertex grip, you can choose:
■ Stretch to move the vertex.
■ Add Vertex to add a vertex on the leader line.
■ Remove Vertex to delete the vertex.

8. Multileader Style Manager
Ribbon: Annotate tab > Leaders panel > Multileader Style Manager
You use the Multileader Style Manager to manage and edit multileader styles. The dialog box and options work almost identically to the Dimension Style Manager. You use this dialog box to create, edit, delete, and set current multileader styles.

9. You use the Modify Multileader Style dialog box to edit the properties associated with the multileader style. Style properties are organized on three tabs with each tab containing specific types of properties. As soon as you exit the Multileader Style Manager, changes you made to an existing style are reflected automatically on any multileaders that are using the style.

Enter p to specify a spline leader.
In the drawing, click a start point for the leader head.
Click the end point for the leader.
Enter your MTEXT content.
In the Text Formatting toolbar, click OK.

13. To define a leader style
