Choose to use either the new or old version of the Array command.

Shawn Summers shared a tip on using AutoCAD 2012's new version of the Array command.

"In AutoCAD 2012, AutoCAD introduced the 3D Array command, which makes 3D arrays possible. Also, a new feature in the command enables users to group arrayed items as one object. For a 3D array (the items are grouped), type 'AR'; for the old 2D array, type '-AR.'"

Notes from Cadalyst Tip Reviewer Brian Benton:
Autodesk changed the Array command with the release of AutoCAD 2012. In previous versions, there were two types of arrays: rectangular and polar. The new version in AutoCAD 2012 is path, arraying your objects along a defined pathway (which could be a line, arc, polyline, etc.).

Another significant difference is the introduction of associated (or grouped) arrays — meaning that all of the objects created in the array behave as if they are one object. This object can be edited by adding or removing rows and columns, or by changing the distances between them. There are also elevations, making the Array command truly three-dimensional. Starting the command in the standard fashions (typing Array or AR on the Command line, or selecting the Array command in the ribbon) will give you access to all of these new options. Typing –AR on the Command line starts the command without any dialog boxes — it will be carried out completely in the Command line. Starting the command in this manner means you will not get the new version of the command.

In these aspects of associativity: "...all of the objects created in the array behave as if they are one object. This object can be edited by adding or removing rows and columns, or by changing the distances between them", for 2-dimensional Rectangular arrays you don't need to have AutoCAD 2012 -- those capabilities have been around for decades, with MINSERT. But having the same with Polar and/or 3D and/or Path-based arrays is new and decidedly useful.
