A one-dimensional array
Array is a dedicated tool for cloning and precisely transforming and positioning groups of objects in one or more spatial dimensions. For each of the three transforms (move, rotate, and scale), you can specify parameters for individual objects in the array, or for the array as a whole. Many results you can get with Array would be laborious or impossible using Shift-Clone techniques.
This is the general procedure. For more details, see these topics:
Creating Circular and Spiral Arrays
To create an array:
Select one or more objects to be in the array.
Choose a coordinate system and transform center.
Choose Array from the Array flyout or the Tools menu to display the Array dialog.
Note: The Array flyout is on the Axis Constraints toolbar, which is off by default. You can toggle display of this toolbar by right-clicking on the main toolbar and selecting Axis Constraints from the Customize Display right-click menu.
Set array parameters on this dialog and click OK.
Generally you should approach Array creation as an iterative process. The dialog settings are not interactive, so you get feedback only after creating the array. By revising the current settings and repeating the array, you develop a solution that meets your needs.
After creating an array and checking its result, undo the array using Edit menu > Undo Create Array or CTRL+Z. This leaves the original selection set in place.
When you create an array, object selection moves to the last copy in the array. By simply repeating current settings, you create a seamless continuation of the original array.
During a session, the program maintains all the dialog settings for your current array.
Array settings are saved only during the current session, not with the file. Be sure you’ve finished an array before you quit the program.
When you create an array, keep these points in mind:
Array is relative to the current viewport settings for coordinate system and transform center.
Axis constraints do not apply, because Array allows you to specify transforms along all axes.
Arrays can be fully animated. By changing the default, you can activate all the transform center buttons, allowing direct animation around either the selection or coordinate center, as well as local pivot. For information about changing the default, see Animating Shift-Rotate and Shift-Scale.
To make an array of a hierarchically linked object, select all the objects in the hierarchy before you click Array.
