6. Uncheck the Display Grid Beyond Limits option and click OK. The
grid no longer fills the screen, and there are blank areas on either
side of the drawing area (see Figure 3.11).

7. Move the cursor from one gridline to another and watch the coordi-
nate readout. The coordinates are still displayed to the nearest half
inch (10 mm), but the gridlines are much more than half an inch
(10 mm) apart.
By default, when you zoom in or out, AutoCAD adjusts the grid spacing to keep
the gridlines from getting too close together or too far apart. In this case, remem-
ber that you found the grid spacing to be ½ (10 mm) by default. If the drawing
area is giving you a view of a 60 ′× 40 (18,000 mm × 12,000 mm) grid with gridlines
at ½ (10 mm), the grid has 1440 (1800) vertical gridlines and 960 (1200) horizon-
tal gridlines. If the whole grid were to be shown on the screen, the gridlines would
be so close together that they would be only about one pixel in size and would sol-
idly fill the drawing area. So AutoCAD adjusts the spacing of the dots to keep the
grid readable. You need to change that spacing to a more usable value.
For the drawing task ahead, it will be more useful to have the spacing set differ-
ently. Remember how you turned on Snap mode, and the cursor stopped at each
gridline intersection? If you set the gridline spacing to 2 (1000 mm) and the Snap
Spacing to 6 (50 mm), you can use Grid and Snap modes to help you draw the out-
line of the cabin, because the dimensions of the outside wall line are in whole feet
