Setting Snap Spacing in AutoCAD

Snap mode restricts the movement of the crosshairs to intervals that you have defined. When Snap is on, the cursor seems to adhere, or “snap,” to an invisible grid. Snap is useful for specifying precise points with the keyboard or pointing device. You control snap precision by setting the X and Y spacing. Snap has a toggle control and can be turned on or off during another command.

Snap spacing does not have to match grid spacing. For example, you might set a wide grid spacing to be used as a reference but maintain a closer snap spacing for accuracy in specifying points. You also can set the grid spacing to be smaller than the snap spacing.
