In the Autodesk® Inventor® drawing environment, with a drawing file open, you will find a button called "CPS View Renamer" on the "CPS Tools" panel of the "Tools" ribbon.

Click this button to rename all detail/section/auxiliary views using sequential lettering in the order that the views were placed.

All of your drawing views will have their letter labels updated automatically.

The installer that ran when you downloaded this app/plug-in from Autodesk App Store has already installed the app/plug-in.

You can unload the plugin without uninstalling it by unchecking the "Loaded/Unloaded" check box associated with the plugin in the Inventor Add-In Manager.

You may have to restart Inventor to completely unload the application.

To remove the plugin completely, Right Mouse Button click and uninstall the application using the Autodesk App Manager tool, located on the Ribbons Tools tab > Options Panel.

To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button.

OR, you can uninstall it from 'Control Panel\Programs\Programs and Features' (Windows 7/8.1/10/11) just as you would uninstall any other application from your system.

Can't relabel views after ZZ. This should not provide an issue in practice, as you would need approximately 600 views to reach ZZ.
