Sets running object snap modes.
The Object Snap tab of the Drafting Settings dialog box is displayed.
If you enter -OSNAP at the Command prompt, the following prompts are displayed.
| Mode | Description | 
|---|---|
| ENDpoint | Snaps to the closest endpoint or corner of a geometric object | 
| MIDpoint | Snaps to the midpoint of a geometric object | 
| CENter | Snaps to the center of an arc, circle, ellipse, or elliptical arc | 
| Geometric CEnter | Snaps to the centroid of any closed polylines and splines | 
| NODe | Snaps to a point object, dimension definition point, or dimension text origin | 
| QUAdrant | Snaps to a quadrant point of an arc, circle, ellipse, or elliptical arc | 
| INTersection | Snaps to the intersection of geometric objects | 
| EXTension | Causes a temporary extension line or arc to be displayed when you pass the cursor over the endpoint of objects, so you can specify points on the extension | 
| INSertion | Snaps to the insertion point of objects such as an attribute, a block, or text | 
| PERpendicular | Snaps to a point perpendicular to the selected geometric object | 
| TANgent | Snaps to the tangent of an arc, circle, ellipse, elliptical arc, polyline arc, or spline | 
| NEArest | Snaps to the nearest point on an object such as an arc, circle, ellipse, elliptical arc, line, point, polyline, ray, spline, or xline | 
| APParent intersection | Snaps to the visual intersection of two objects that do not intersect in 3D space but may appear to intersect in the current view | 
| PARallel | Constrains a new line segment, polyline segment, ray or xline to be parallel to an existing linear object that you identify by hovering your cursor | 
| NONe | Turns off object snap modes | 
For more information on each of these object snap modes, see the Object Snap tab of the Drafting Settings dialog box.
