After choosing the method you want to use, it is time to pick the values
and axis used to place each duplicate. For instance, in the X field, you
can set the value used for copies in the X-axis. If you use a value of 1
for the X and 3 for Count, you will get five copies on the X-axis.
Using the Fixed Count type, they will repeat three times in the X-axis
(Figure 4.21).
Figure 4.21 - Copies in the X-axis
Using those same values makes three copies with a distance of one unit
in the X-axis if you choose Fit Length.
A single Array Modifier will only make copies in either a row or column of
objects. You need two Arrays to get a bi-dimensional pattern (rows and
columns). For instance, we can use one Array for the X-axis and other
for the Y-axis (Figure 4.22).
