If enabled AutoCAD2013 grid, the grid lines may be displayed at the specified row and column spacing AutoCAD2013 uniformly distributed in the drawing window, shown in FIG..As can be seen, the grid lines may be used to represent the coordinate position of the drawing, with the effect similar to graph paper, but these will not AutoCAD2013 grid lines printed on the sheet.
Tip: AutoCAD2013 drawing, using the grid functions can easily achieve alignment between the pattern, determining a distance between the graphic object.
A, AutoCAD2013 enable grid function
Whether to enable the grid can be achieved by following a switching function.
1.Press the keyboard [F7] key to enable or disable the grid.
2.Click the icon on the status bar AutoCAD2013, when the icon changes to a green icon, a grid feature is enabled.
Tip: AutoCAD2013 drawing process, you can always enable or disable the grid functions as needed.
Second, set the grid
"Drafting Settings" dialog box is used to open a command DSETTINGS.Or on AutoCAD2013 status bar (grid) at the right-click button, select "Settings" from the shortcut menu, you can open AutoCAD2013 "Drafting Settings" dialog box.
Turn on or off the grid.You can also "grid" click on the status bar, press the F7 key, or use GRIDMODE system variable to turn on or off grid mode.
Set of two-dimensional grid pattern in context.You can also use GRIDSTYLE system variable is set grid style.
 Two-dimensional model space
The grid style AutoCAD2013 two-dimensional model of the space to a grid point.
The grid pattern block editor to set grid point.
[Drawing / layout]
The grid style layout drawings and AutoCAD2013 set point grid.
Display of the control grid helps to visualize the distance.
Note LIMITS command and control system variables GRIDDISPLAY grid limits.
Grid spacing [X]
Grid spacing in the direction designated X.If the value is 0, the grid a "capture the X-axis pitch" set of values.
Y grid spacing 
Grid spacing in the Y direction designated.If the value is 0, the numerical grid set "capture Y-axis pitch" of.
[Number of] the grid for each main line
Specify the primary grid lines with respect to the time frequency grid lines.
Show grid lines in the following without displaying the grid point where:
AutoCAD2013 GRIDSTYLE set to 0 (zero).
AutoCAD2013 LT: SHADEMODE set to "hide".
Control the appearance of grid lines.
Adaptive grid 
When reduced, the grid density limit.
PERMIT less than the pitch of the grid subdivided '':
When enlarged, generate more smaller gridline spacing.Determining the frequency of the main frequency of these grid lines of grid lines.
[Show Grid beyond the boundaries]
Display command specifies the grid beyond the region LIMITS.
[Follow] Dynamic UCS
XY plane of the grid plane to follow the change of the dynamic UCS.
Three, AutoCAD2013 grid behavior settings
In the "grid behavior" option group "Snap and Grid" tab, if you select "adaptive grid", when the narrow display graphics, will automatically change the grid density of the grid is not too close.If the "allow subdivided grid spacing is less than" check box, when the display pattern is magnified, can add some of the grid lines.If you select "show outside the bounds of ∷ box, AutoCAD2013 drawing will be displayed in the entire screen grid only displays a grid in the drawing the boundaries set by the LIMITS command.
Four, AutoCAD2013 drawing using a grid pattern Example Procedure:
First set the grid spacing and capture.Open AutoCAD2013 "Drafting Settings" dialog box."Snap and Grid" tab in the dialog box, and the snap spacing grid spacing are set to 5, and enable the capture function and the grid, shown in FIG..
Click the "OK" button to close the dialog box, AutoCAD2013 show grid lines on the screen.LINE command pattern drawn with this point, will only see the cursor is located in each raster line, it is possible to readily determine the position of each end of the straight line (the distance is determined by the number of grids, steps are omitted); present a graphical view drawing composed of simple linear, and the pattern size of each of integral multiples of 5.Thus, the use of capture AutoCAD2013 grid function, without entering the coordinate values can be readily determined end position of each line.
