Specifies a precise point at a location on an object. 
 
  Within a command, at a prompt to locate a point, specify an object snap 
 When you specify an object snap, the cursor snaps to the specified point on an object closest to the center of the cursor. By default, a marker and a tooltip are displayed when you move the cursor over the object snap location on an object. 
Specify a Single Object Snap
 
   
  If you specify a single object snap, it stays in effect only for the next point you specify. 
  
 
  You can specify an object snap with any of the following methods: 
  
- Enter a object snap by typing its name. To see a list of valid object snaps, refer to the OSNAP command or the Drafting Settings Dialog Box. 
	 
 
- Click an object snap from the Object Snap toolbar. 
	 
 
- Click an object snap from the Object Snap shortcut menu. You can display this shortcut menu by pressing SHIFT while you right-click. 
	 
 
 
   
 
 
Use Running Object Snaps
 
   
  Using the OSNAP or DSETTINGS commands, you can specify a set of 
	 
running object snaps. Running object snaps are one or more object snaps that remain in effect as you work. 
  
- To turn running object snaps on and off, click the Object Snap button on the status bar or press F3. 
	 
 
- Press TAB to cycle through the object snap possibilities before you specify the point. 
	 
 
- To turn off running object snaps for the next point only, specify the None object snap.
