When you upload a DWG file that contains "Xrefs" (cross-references to external files), we will process the file for visualisation. However, only the data from the uploaded file will be rendered, and any data contained in the cross-referenced files will not be included.
If you need to include data from the cross-referenced files, you should upload a federated file that incorporates all necessary data. For guidance on how to save DWG files without Xrefs, please refer to Autodesk's instructions here.
If you have any questions or need further assistance, feel free to reach out to our support team.
