File uploads in 2026.9

Check your workspace’s upload mode before uploading a file in 2026.9. Some formats require legacy/compatibility mode, which ends on 1 November 2026. Tekla Structures uploads are available where enabled.

​

Breaking change: supported file formats

This affects both drag-and-drop uploads in the web app and uploads through the API. Existing models stay readable; the change affects importing new files and uploading new versions.

​

Supported formats by upload mode

Availability depends on the conversion services enabled for your workspace. In default 2026.9 mode, cloud file sync supports the same file formats as file uploads.

​

Additional format: Tekla Structures

2026.9 adds support for Tekla Structures model packages (.tekla) and model databases (.db1) on deployments where Tekla uploads are enabled. This is not enabled by default; confirm availability with Speckle before relying on it for your workflow. Use the complete model folder when uploading a Tekla model to preserve profiles, shapes, and materials.

​

Upload a Vectorworks file

If your design lives in Vectorworks, you can upload the .vwx file to publish it without opening Vectorworks or installing its connector. For the steps, see Upload a file. The Vectorworks connector publishes the objects you select; an upload publishes the 3D content of every design layer.

​

Files that convert

Speckle reads files last saved in Vectorworks 2021 through 2027. Files from other releases are not supported yet.

​

What is published

• 3D objects on every design layer, including design layers hidden in the document, grouped by story, layer, and type.
• Each object’s name, type, object properties, and IFC properties. An object whose 3D geometry Speckle cannot read arrives with its properties and no geometry.

These parts of the document are not published:

• Objects in a class that is hidden in the document.
• Sheet layers.
• 2D-only objects, such as callouts, data tags, and section lines.

​

If a Vectorworks upload fails

​

Upload a Solibri file

Upload a Solibri .smc file to publish the whole federation saved in it, without opening Solibri or installing a connector. You do not need the original IFC files alongside it. For the steps, see Upload a file. After conversion, open the model in Speckle to view its geometry and inspect its properties.

​

Files that convert

Files saved in Solibri 9.12 and 26.6 have been verified. Speckle attempts to read .smc files from other releases, but their compatibility has not been verified. .smv and .smct files are not supported.

​

What is published

• The saved federation, grouped by source model and its spatial hierarchy.
• Component geometry with original colours and transparency.
• Source properties, Solibri-derived properties, and saved classification results, including group, zone and system memberships.

These parts of the document are not published:

• Rule sets and checking results.
• Presentations.
• Issues and BCF data.

An upload reads the data saved in the file; it does not run Solibri checks or re-evaluate classifications.

​

Recover missing Solibri geometry

For the closest match to Solibri’s 3D view, save the file with Save 3D Representations with Model enabled under Settings > 3D in Solibri. Let the 3D view finish drawing before saving. When the file has no saved 3D representation for a component, Speckle tries to rebuild its geometry. This takes longer and can produce approximate geometry. Components that cannot be rebuilt retain their properties but have no geometry. Open the file in Solibri, enable the setting, let the 3D view draw, save and upload it again.

​

Recover a missing Federated Floor property

A component’s Federated Floor property is included only if Solibri computed and saved it. To populate it, open the file in Solibri, group the model tree by Locations, and use Save As before uploading again. Some components may still have no federated floor.

​

If a Solibri upload fails

If the upload fails, check that the file opens in Solibri and save it again before retrying. Contact Speckle support if it still fails.

​

Update an affected workflow

If your workspace uses legacy/compatibility mode, you can continue uploading the affected formats until compatibility mode ends on 1 November 2026. Before moving to the default 2026.9 mode, export to a supported format or publish through a supported desktop connector. Check the resulting model before switching your workflow: uploads and connector publishing can produce different geometry and properties. See Uploads and connectors produce different datasets. For the upload steps, see Upload a file. For programmatic uploads, see Uploading IFC and other files. Use the supported formats on this page for 2026.9.

​

Temporary compatibility option

Legacy mode, also called compatibility mode, retains direct upload support for the affected formats when the older conversion service is enabled. Ask Speckle to confirm availability for your workspace. It ends for every workspace on 1 November 2026. This exception applies to direct uploads, not cloud sync. Compatibility mode affects the entire workspace’s upload and sync routing; it is not a per-file fallback. DGN uploads are not supported in compatibility mode. For availability, the 1 November 2026 end date, and how to request it, see Compatibility mode for ACC sync and uploads.
