At the Specify dimension line location or [Mtext/Text/Angle]: prompt, you see
the diameter dimension drag along the circle as you move the cursor. If you move the
cursor outside the circle, the dimension line and text also move outside the circle. (See the
top image in Figure 11.27.)

a circle
If the dimension text can't it in the circle, AutoCAD gives you the option to place it outside
the circle as you drag the temporary dimension to a horizontal position.
4.
Place the cursor inside the circle so the dimension arrow points in a horizontal direction,
as shown in the bottom image of Figure 11.27.

With the text centered, click the mouse.
The Radius tool found in the Linear Dimension flyout on the Tool Sets palette gives you a
radius dimension, just as the Diameter tool provides a circle's diameter. You can also type
DRA
↵.
Figure 11.28 shows a radius dimension on the inside of the circle, but you can place it outside
in a manner similar to how you place the diameter dimension. The Center Mark tool on the
expanded Dimensions tool group places a cross mark in the center of the selected arc or circle.
