To run the Revit add-on, follow these steps:

1. Launch Revit and navigate to the Add-Ins tab in the ribbon.
2. From the External Tools menu, select the RevitMaterialScanner command.

The add-on will then:

• Iterate through all the available materials in the Revit file.
• Display a dialog box showing the number of duplicated materials and appearance assets, if any.
• Prompt the user to delete the duplicated materials and appearance assets.

If you choose to delete the duplicated materials, the add-on will check if these entities are used within the Revit model. It will only delete the entities that are not in use.

The installer that ran when you downloaded this app/plug-in from the Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin. You may need to restart the Autodesk product to activate the app/plug-in.

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, click Control Panel > Programs > Programs and Features (Windows 10/11) and uninstall as you would any other application from your system.

This add-on currently supports Revit versions 2022, 2023, 2024, and 2025.

The add-on does not consider "Thermal" and "Physical Assets" as of now, for duplicated material detection and removal.
