Supported and Unsupported Files Types
With Desktop Connector, you can upload and gather references for various design file types. However, not all file types support reference gathering. Additionally, some files are excluded from being uploaded due to factors such as incompatibility with Docs or other issues.
Supported File Types
Desktop Connector supports all file types that each connector's data source supports. For a list of all supported files, refer to the following links:
- BIM 360 Docs supported files
- Autodesk Docs (ACC) supported files
- Autodesk Fusion supported files
- Autodesk Drive supported files
Design Files with Reference Gathering Support
Desktop Connector can analyze the following design files to understand and gather their referenced files.
Use Reference Explorer to visualize all referenced files and their relationships. To learn how to upload design files to Docs with references, refer to Docs - Upload Files and References.
Make sure you have the latest release installed for the best performance. You can use the search bar at the top of the table to narrow down results in the table.
