You can display a reference grid consisting of a regular pattern of dots. This grid is similar to drawing on a sheet of nonreproducing grid paper. Although the reference grid is visible on the screen, it does not print as part of the drawing, nor does it affect where you can draw.
The reference grid extends only to the limits of the drawing, helping you to visualize the boundary of your drawing and to align entities and visualize distances between entities. You can turn the grid on and off as needed. You can also change the spacing of the grid at any time.
TIP To toggle the grid display on and off at any time, double-click the GRID setting on the status bar, click the Reference Grid tool () on the Settings toolbar, or press F7.
