Total Number of Items and Angle to Fill
Specify the included angle to fill with all items in the fi
Fill Angle
ribbon text box or
use the
Fill angle
option. For example, enter
360
to create a complete circular array, as
shown in Figure 12-17B, or enter
180
to create a half circle array. AutoCAD converts a
negative value entered in the
Fill Angle
ribbon text box to positive. However, a negative
value entered while using the
Fill angle
option changes the array to occur in a clockwise
direction. You will learn more about polar array direction later in this chapter. If you
do not know an exact angle, enter an equation or formula in the
Fill Angle
ribbon text
box, or apply the
Expression
option at the appropriate prompt of the
Fill angle
option.
NOTTE N OTE OT OT
The
Angle between
and
Fill angle
options allow you to enter a numeric
value or specify points for the angle between items or fi ll angle. fi
Adding Rows
Use the text boxes in the
Rows
ribbon panel, or apply the
ROWs
option, to add
multiple rows during the array. See Figure 12-18. Row count determines the total
number of rows in the array. Figure 12-17B shows the default array with one row.
Figure 12-18 shows an array with three rows. If you do not know an exact count, enter
an equation or formula in the
Row Count
ribbon text box, or apply the
Expression
option at the appropriate prompt of the
ROWs
option.
You can specify row spacing or total row distance. Row spacing is the distance
from a point on an item in a row to the corresponding object point in the adjacent row.
Enter a positive, nonzero value. If you do not know an exact spacing, enter an equation
or formula in the
Row Spacing
ribbon text box, or apply the
Expression
option at the
appropriate prompt of the
ROWs
option.
The total row distance is the total spacing from a point on an item in the first row fi
to the corresponding object point in the last row. To specify the total row distance,
use the
Total Row Distance
ribbon text box or apply the
Total
option at the appropriate
prompt of the
ROWs
option. Enter a positive, nonzero value.
NOTTE N OT OT TE
The
ROWs
option allows you to enter a numeric value or specify points
for row spacing or total distance.
