Object snaps constrain point specification to exact locations, such as a midpoint or an intersection, on existing objects. Using object snaps is a quick way to locate an exact position on an object without having to know the coordinate or draw construction lines. For example, you can use an object snap to draw a line to the center of a circle or to the midpoint of a polyline segment. You can specify an object snap whenever AutoCAD LT prompts for a point.
If AutoSnap is turned on, AutoCAD LT displays a marker and a SnapTip whenever you move the target box over a snap point. This feature provides a visual clue that indicates which object snaps are in effect.
There are a variety of ways to turn on object snaps. If you choose an individual object snap tool or enter its name on the command line, the snap stays in effect only for the next point you specify. You also can set running object snaps, that is, one or more object snaps that remain in effect as you work. Choose None to turn off both single and running object snaps.
