Troubleshooting and Logs

01. Why is the Connector not starting when I click the Data Exchange command?

If you encounter difficulties starting or using the Connector, it may be due to incompatible plugins that are enabled within the Revit software. They could cause such issues with Revit Connector. We advise reviewing and potentially disabling these plugins and then restarting the Connector. Monitor any changes in the Connector behavior and if issues persist, contact us through the support channels Beta User Forums or Public Forum with the list of enabled plugins for further troubleshooting. You can also email us at data.exchange.support@autodesk.com.

02. Are exchanges files?

Exchanges are not files.

03. Why do I need to host exchanges in the Autodesk Docs even though I can create them with the Autodesk Data Exchange Connector for Revit on my computer?

They are hosted in the Autodesk Docs to allow collaboration among team members across various disciplines. They also allow your software to use services, download data from the broader Autodesk Platform Services ecosystem, and exchange information using various tools such as 3D softwares, spreadsheet processors, and databases.

04. Why does it have a size of zero in Autodesk Docs?

The exchange files in Autodesk Docs or BIM 360 serve only as references and do not contain any data. They point to the exchange information stored at a granular level.

05. Is it necessary to uninstall the previous version of Connector to install the updated version?

Yes. It is necessary to uninstall the previous version before installing the updated version.

View Log Files

Log files contain information about operations that have taken place on the server and can be used to diagnose various problems. You can view log files to diagnose the failures or errors while using the Connector and share them with the support team for further analysis. To locate the log files for specific versions, you can either navigate to the following directories or type the corresponding path in the Windows Search bar and press Enter.

  • Autodesk Data Exchange Connector for Revit 2026: %AppData%\Revit2026-Connector\1.8.0\logs
  • Autodesk Data Exchange Connector for Revit 2025: %AppData%\Revit2025-Connector\1.8.0\logs
  • Autodesk Data Exchange Connector for Revit 2024: %AppData%\Revit2024-Connector\1.8.0\logs
  • Autodesk Data Exchange Connector for Revit 2023: %AppData%\Revit2023-Connector\1.5.0\logs

Enabling Detailed Logs

In Autodesk Revit, detailed logging is a powerful tool to troubleshoot issues, understand workflows, and optimize performance. By setting up a user-specific environment variable, you can enable or disable the creation of detailed logs for the Revit File Data Exchange (FDX) Connector. This article will guide you through the process of adding the 'RevitFDXLogs' variable and explain how to locate and utilize the logs for your benefit. To enable detailed logging in Autodesk Revit, you need to add an environment variable specific to your user account. You can view log files to diagnose the failures or errors while using the Connector and share them with the support team for further analysis. Follow these steps:

  1. Open the System Properties dialog by right-clicking on This PC or Computer on your desktop or in File Explorer, and select Properties.
  2. Click Advanced system settings.
  3. In the System Properties dialog, click the Environment Variables... button.
  4. Under 'User variables for '[your username]', click on the New... button to create a new variable.
  5. In the 'Variable name' field, enter RevitFDXLogs exactly as shown.
  6. In the 'Variable value' field, type Yes to enable logging or No to disable it.
  7. Click OK to save the variable, and OK again to close the Environment Variables dialog.
Note: the variable name is case-sensitive.

Accessing the Logs:

Once you have enabled detailed logging, the logs can be found in the following locations:

  • Create Exchange Log: Navigate to AppData\Revit-Connector<ConnectorVersion>\logs\FDXLogs. Here you will find a JSON file generated during the creation of an exchange.

For example, AppData\Revit2025-Connector\1.3.0\logs\FDXLogs\ed924940-7cdf-33dc-9b14-227847827641.

  • Load Exchange Log: Navigate to AppData\Revit-Connector<ConnectorVersion>\logs\FDXLogs<ExchangeId><RandomUniqueId>. Here you will find a JSON file generated during the loading of an exchange.

For example, AppData\Revit2025-Connector\1.3.0\logs\FDXLogs\ed924940-7cdf-33dc-9b14-227847827641\3c2944a9-6d30-4213-abe9-04d0bf33102e.
