Use object snaps to
specify precise locations on objects. 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
you are prompted for a point. By default, a marker and a tooltip
are displayed when you move the cursor over an object snap location
on an object. This feature, called AutoSnap™,
provides a visual clue that indicates which object snaps are in
effect.
For a list of object snaps, see OSNAP.
Specify an Object Snap
To
specify an object snap at a prompt for a point, you can
- Press Shift and right-click to display
the Object Snap shortcut menu
- Click an object snap button on the Object
Snap toolbar
- Enter the name of an object snap at the
Command prompt
- On the status bar, right-click the object
snap button
When you specify an object snap at a prompt
for a point, the object snap stays in effect only for the next point
that you specify.
NoteObject snaps work
only when you are prompted for a point. If you try to use an object
snap at the Command prompt, an error message is displayed.
Use Running Object Snaps
If
you need to use one or more object snaps repeatedly, you can turn
on running object snaps. For example,
you might set Center as a running object snap if you need to connect
the centers of a series of circles with a line.
You can specify one or more running object snaps
on the Object Snaps tab in the Drafting Settings dialog box, which
is accessible from the Tools menu. If several running object snaps
are on, more than one object snap may be eligible at a given location.
Press Tab to cycle through the possibilities before you specify
the point.
Click the OSNAP button on the status bar or
press F3 to turn running object snaps on and off.
NoteIf you want object
snaps to ignore hatch objects, set the OSOPTIONS system variable
to 1.
To snap to a geometric
point on an object
- At the prompt for a point, hold down
Shift and right-click in the drawing area. Select the object snap
you want to use.

cursor automatically locks onto the snap location you selected,
and a marker and tooltip indicate the object snap point.
- Select an object.
The cursor snaps to the eligible location closest
to your selection.

Object Snap tab, select the object snaps you want to use.
