Choose Home tab→Annotation group→Bolt Hole Circle 
.
On the Bolt Hole Circle command bar, click the settings you want to use.
Click points—either a center point and radius or three points, depending on the setting you selected in the previous step—to define the bolt hole circle location.

When a bolt hole circle annotation becomes detached, you can drag it to a new circle along the bolt hole circle radius area. You also can delete it and then recreate it.
