Create and Manage Customization Files
Customization (CUIx) files are used to store commands, user interface elements,
and references to partial CUIx files and AutoLISP files. CUIx files can be
designated as main, partial, or enterprise.
Basics of Customization Files
Customization files are loaded into AutoCAD to define elements that make
up the user interface and are edited using the Customize User Interface (CUI)
Editor.
AutoCAD comes with several different CUIx files that can be tailored to your
work environment. AutoCAD has two main designations for CUIx files, main
and enterprise; by default AutoCAD uses a main CUIx file. You can customize
the files that come with AutoCAD or you can create your own CUIx files from
scratch using the Transfer tab in the Customize User Interface (CUI) Editor.
When customizing the CUIx files that come with AutoCAD or creating your
own CUIx files, the Customize User Interface (CUI) Editor creates a backup
copy of the file when you first start making changes to the CUIx file. This
allows you to restore the file if you delete something that you wanted to keep.
If you happen to modify a CUIx file that comes with AutoCAD, you can reset
it back to its original state.
The Customize User Interface allows you to not only create new user interface
elements and commands from scratch, but you can also copy existing user
interface elements and commands to modify them.
To set the working CUIx file
Before you can add custom commands to a CUIx file, you must set a CUIx
file as the working file.
1 Click Manage tab ➤ Customization panel ➤ User Interface.
2 In the Customize User Interface Editor, Customize tab, Customizations
In <file name> pane, click the down arrow on the Customization Files
drop-down list.
3 Select Main Customization File <file name> or one of the loaded CUIx
files to set it as the working CUIx file.
