When you array elements, you create multiple copies of an element at the same time. You can create an array in a single row or column, or a layout of rows and columns. You can also control the spacing between elements in the array, and the array's rotation angle. Example
To array an element:
Select the element you want to array.
Right-click and select Array, or select Edit > Modify Elements > Array.
In the Number of Rows box, type the number of horizontal rows you want or use the arrows to select a value.
In the Number of Columns box, type the number of vertical columns you want.
In the Distance Between Rows box, type the spacing you want between rows. This determines the distance between elements appearing in columns (vertical spacing).
In the Distance Between Columns box, type the spacing you want between columns. This determines the distance between elements appearing in rows (horizontal spacing).
In the Array Rotation Angle box, type the degree of rotation for the array.
Click OK. The array is created.
Note: The Array tool is only available for certain elements.
