Snap to Locations on Objects (Object Snaps)
Instead of entering coordinates, you can specify points relative to existing
objects such as endpoints of lines or center points of circles.
Use Object Snaps
Object snaps constrain point specification to exact locations, such as a mid-
point 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 prompts for a
point. For a list of object snaps, see
OSNAP in the Command Reference.
If AutoSnap™ is turned on, AutoCAD displays a marker and a tooltip when-
ever 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 on the toolbar 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.
Snap to a Single Point
When you specify an object snap, the cursor changes to an object snap target
box. When you select an object, AutoCAD snaps to the eligible snap point
closest to the center of the target box, or aperture.
The object snap buttons are located on the Object Snap flyout on the
Standard toolbar.
