'SNAP Command

Restricts cursor movement to regular intervals

Command line: snap

Snap spacing or ON / OFF / Aspect / Rotate / Style <current>: Specify a distance, enter an option, or press ENTER

The points you enter with a pointing device can be locked into regular intervals on an invisible rectangular snap grid. You can rotate the snap grid, set differing X and Y spacing, or choose an isometric format.

A change in the snap grid affects only the coordinates of new points. Objects already in the drawing retain their existing coordinates.

The snap grid is invisible. Use the GRID command to display a separate visible grid of dots. Set the spacing of the two grids to equal or related values.

Spacing (SNAP)

Activates Snap mode with the value you specify.

On/Off (SNAP)

• On. Activates Snap mode using the current snap grid resolution, rotation, and style.
• Off. Turns off Snap mode but retains the values and modes.

Specifies different spacing in the X and Y directions. This option is not available if the current snap style is Isometric.

Horizontal spacing <current>: Specify a distance or press ENTER
Vertical spacing <current>: Specify a distance or press ENTER

Rotate (SNAP)

Sets the rotation and base point of the snap grid with respect to the drawing and the display screen. The base point sets the origin point of the snap grid, shifting it to a specified location. You can specify a rotation angle between -90 and 90 degrees. A positive angle rotates the grid counterclockwise about its base point. A negative angle rotates the grid clockwise.

Base point <current>: Specify a point or press ENTER
Rotation angle <current>: Specify an angle or press ENTER

Angle adjusted to value.

Style (SNAP)

Selects the format of the snap grid, which is standard or isometric.

Standard / Isometric <current>: Enter s or i or press ENTER

Standard

Displays a rectangular grid that is parallel to the XY plane of the current UCS. X and Y spacing may differ.

Spacing / Aspect <current>:Specify a distance, enter a, or press ENTER

Isometric

Displays an isometric grid, where the grid points are initially at 30- and 150-degree angles.

Vertical spacing <current>: Specify a distance or press ENTER

The ISOPLANE command determines whether the crosshairs lie in the top isometric plane (30- and 150-degree angles), the left isoplane (90- and 150-degree angles), or the right isoplane (30- and 90-degree angles).

Isometric snap can be rotated but cannot have different horizontal and vertical spacing.

• Spacing. Changes the overall spacing.
• Aspect. Changes the horizontal and vertical spacing separately.

System Variables: SNAPBASE stores the origin point of the snap grid. The grid display is also changed after a redraw or other viewing command.
