Toggles entity snap modes at the command line (short for "object snap").

Accessing the Command

command bar: -osnap

transparent: '-osnap

shortcut: F3

aliases: esnap, -os

status bar: ESNAP

: -osnap

Prompts you in the command bar:

Snaps: NEArest/ENDpoint/MIDpoint/CENter/GeometricCEnter/PERpendicular/TANgent/QUAdrant/INSertion/POInt/INTersection/APParent/ON/<OFF>: (Enter an option, or press Enter to toggle entity snaps on or off.)

The following entity snaps work with 3D solid models:

Endpoint
Midpoint
Nearest

Command Options

Option	Description
NEArest	Toggles nearest entity snap mode. Snaps to the nearest point on any entity. Can also be toggled with the Nearest command.
ENDpoint	Toggles endpoint entity snap mode. Snaps to the endpoints of open entities, such as lines, arcs, open polylines, and open splines. Can also be toggled with the Endpoint command.
MIDpoint	Toggles midpoint entity snap mode. Snaps to the midpoint of open entities. Can also be toggled with the Midpoint command.
CENter	Toggles center entity snap mode. Snaps to the center of circular entities, such as circles, arcs, and polyarcs. Can also be toggled with the Center command.
GeometricCEnter	Toggles geometric center entity (GCenter) snap mode. Snaps to the centroid of any closed polylines and splines, planar 3d polylines, regions and planar faces of 3D solids. Can also be toggled with the GCenter command.
PERpendicular	Toggles perpendicular entity snap mode. Snaps to the perpendicular of one entity to another. Can also be toggled with the Perpendicular command.
TANgent	Toggles Tangent entity snap mode. Snaps to the tangencies of circular entities. Can also be toggled with the Tangent command.
QUAdrant	Toggles quadrant entity snap mode. Snaps to the quadrant points of circular entities, such as circles, arcs, and polyarcs. Can also be toggled with the Quadrant command.
INSertion	Toggles insertion entity snap mode. Snaps to the insertion point of blocks and text. Can also be toggled with the Insertion command.
POInt (Node)	Toggles node entity snap mode. Snaps to point entities. Can also be toggled with the Node command.
INTersection	Toggles intersection entity snap mode. Snaps to the intersection of any pair of entities. Can also be toggled with the Intersection and 3dIntersection commands.
APParent	Toggles Apparent entity snap mode. Snaps to the apparent intersection of entities in 3D space. Can also be toggled with the Apparent and 2dIntersection commands.
EXTension	Toggles extension entity snap mode. Snaps to the intersection of open entities, as if they were extended to the point of intersection. Can also be toggled with the Extension command.
PARallel	Toggles parallel entity snap mode. Snaps to the parallel point of entities. Allows to draw lines, polyline segments, xlines and rays parallel to another entity. Can aso be toggled with the Parallel command.
ON	Turns all entity snap modes on.
OFF	Turns all entity snap modes off. Modes can also be turned off with the None command.
