This dimension tool is used to add a radius dimension to a circle or arc, but it is meant for a situation where the center of the arc or circle is located off the drawing sheet or far from the circumference of the circle or arc. This dimension tool allows you to specify the location of the center for those kinds of circles or arcs using the center location override and a zigzag line is added to the radius line, which indicates that the actual center is located toward the direction of the zigzag line. 

In the following example, we will add a jogged radius to an arc:

1. Select Jogged from the Dimension drop-down menu and click on the arc or circle on which you want to add the jogged radius.
2. When the command line prompts you to specify the center location override, click at a point toward the center of the circle or arc, and then click at a point to place the dimension, and then again to place the jogged line.

3. The final dimension that you will get will look like the one shown in the following screenshot:

This was an overview of the dimension tools we have in AutoCAD. You can use these tools to add almost any kind of dimension to your drawings. There are also some specialized kind of dimension tools, such as baseline and ordinate, which we discuss later in this chapter. In the next section, we will discuss the Dimension tool, which can make almost all of the dimension types we just discussed.
