I have received a lot of users who are using one or all of these applications AutoCAD, AutoCAD Architecture, AutoCAD MEP, AutoCAD Mechanical or Civil 3D, and they complain about the new Array command. As of 2012 the Array command went from specifying all your settings within the Array dialog box, to specifying the settings directly at the command line.
If you want to use the the array dialog box you can type ARRAYCLASSIC at the command line. Now the next question I get is I want to be able to click it from the ribbon or from my toolbars so I have an answer for this;
How to create a custom command:
At the command line type CUI to go into your Customization User Interface editor.
You will see "Command1" in the command list. Select on it then right click and click on Rename.
Now that you have created a new command, you will need to modify the macro from the Properties on the right. You will need to type ^C^C_ARRAYCLASSIC
you can then add an icon from the Images section below so that you have an icon once its placed on the ribbon or toolbar. I found the original Array commands icon, then clicked on the Edit button to add/modify the icon to look different. Its nothing special but sometimes just adding a color to it will separate it from the other icons. Once you are finished you just need to click on the Save...button and give your icon a name and click the OK button > then the close button. From within the Customize User Interface editor, click the Apply button. But we are not done yet.
You will now see your new command in the Command List on the left. You will now add this to your toolbar or ribbon by simply dragging and dropping it into place. I want to add mine to my ribbon in the same spot that the Array command is at which is on the Home tab > Modify panel. (You can add it anywhere you want)
While still in the CUI you will expand Ribbon under the upper left panel called "Customizations in All Files" , then expand Panels and look for the Home-Modify. (depending on which workspace you are using you will expand Home - Modify 2D or 3D)
If you are questioning which Row, or sub-panel to put your new command under you can simply click on "Row 1" and on the upper right side you will see a "Panel Preview" so you will be able to tell about where you will be putting it.
