You can specify the total number of items and angle between items or the total
number of items and angle to fill. Use the text boxes in the fi
Items
ribbon panel, or
apply the Items,
Angle

Fill angle
options. Item count determines the total
number of items in the array. Figure 12-17B shows the default array of six items. If you
do not know an exact count, enter an equation or formula in the
Item Count
ribbon text
box, or apply the
Expression
option at the appropriate prompt of the
Items
option.
Total Number of Items and Angle between Items
Specify the included angle between adjacent items, as shown in Figure 12-17B,
in the
Angle between Items
ribbon text box, or use the
Angle between
option. Enter
a positive, nonzero value. If you do not know an exact angle, enter an equation or
formula in the
Angle between Items
ribbon text box, or apply the
Expression
option at
the appropriate prompt of the
Angle between
option.
