Base Point Specifies a base point for positioning the objects in the array.
Key Point For associative arrays, specifies a valid constraint (or key point) on
the source objects to use as the base point. If you edit the source objects of
the resulting array, the base point of the array remains coincident with the
key point of the source objects.
Rows
Specifies the number and spacing of rows, and the incrementing elevation
between them.
Number of Rows Specifies the number of rows in the array.
Expression Derives a value using a mathematical formula or equation.
Total Specifies the total distance between the first and last rows.
Incrementing Elevation Specifies the amount of elevation change between
each successive row.
Columns (Rectangular Arrays)
Specifies the number and spacing of columns.
Number of Columns Specifies the number of columns in the array.
Distance Between Columns Specifies the distance between columns.
Expression Derives a value using a mathematical formula or equation.
Total Specifies the total distance between the first and last columns.
Levels
Specifies the number and spacing of levels (for 3D arrays).
Number of Levels Specifies the number of levels in the array.
Distance Between Levels Specifies the distance between the levels.
Expression Derives a value using a mathematical formula or equation.
Total Specifies the total distance between the first and last levels.
Method (Path Arrays)
Controls how to distribute items along the path.
 Divide. Redistributes items to divide evenly along the length of the path.
 Measure. Maintains current spacing when the path is edited, or when
the number of items is edited through grips or the Properties Inspector.
When the number of items is edited using ARRAYEDIT, you are prompted
to redefine the distribution method.
