This is 2026.9 documentation. Coverage here is incremental: a page exists only where 2026.9 differs or is newly documented. For any other topic, switch to Current (2026.8 and earlier) in the version selector.
If you publish and load through Speckle connectors, your day-to-day work stays the same in 2026.9. After you update a connector, new publishes use the new format going forward. Most people do not need to do anything beyond updating their connector. Navisworks has no 2026.9 installer — see Navisworks in 2026.9. For how to publish and load in each design tool today, see Connectors. For dates and the full workspace steps, see Speckle’s data model is changing. For a compact before-and-after table, see Compare 2026.8 and 2026.9. This page covers the shared data-format change for connectors. 2026.9 pages exist for Revit, Grasshopper, Power BI, Navisworks, and Trimble Connect. For any other design tool, use the connector guides under Current in the version selector — see Design tools without a dedicated page.

​
File uploads in 2026.9

The default upload path accepts fewer file formats in 2026.9. STL and the other affected formats remain supported for direct uploads in legacy/compatibility mode until it ends on 1 November 2026. See File uploads in 2026.9 for supported formats and alternatives.

Design tools in 2026.9

​
Design tools without a dedicated page

These tools have no dedicated 2026.9 page. Update the connector when a 2026.9 build exists. Publish and load stay the same. How-to remains under Current in the version selector — see Connectors.
  • ProjectWise on-prem, ProjectWise Cloud, and other cloud integrations without a 2026.9 page (ACC, Databricks, Snowflake)
  • DGN / MicroStation / OpenRoads
  • Tekla Structural Designer
  • Rhino, SketchUp, Archicad, Blender, Civil 3D, Plant 3D, AutoCAD, ETABS, and Tekla Structures
  • Third-party connectors (Vectorworks, Karamba3D, ShapeDiver)
A 2026.8-or-earlier connector cannot load data published by a 2026.9-or-newer connector. Check the receiving connector’s supported data format before updating a shared workflow.
Vectorworks does not yet support loading the 2026.9 data format. See Why can’t I load a model into Vectorworks anymore?.
Compatibility mode applies to ACC sync and drag-and-drop uploads. It does not change the data format published or loaded by desktop connectors.

​
What stays the same

You still publish and load through your connectors, and you still view and share in the web app. Your existing connectors keep working. Models you already published stay readable.

​
What changes

After your project moves to the new data format, publish, load, and view are faster. New publishes from an updated connector use the new format going forward. A 2026.8 Navisworks publish still uses the pre-2026.9 data format; the server may convert it, but that is not guaranteed.

​
What you should do

Update your connector from 1 September 2026, and no later than 1 November 2026. Publish and load as usual after updating. New publishes use the 2026.9 format; existing models stay readable.
Navisworks has no 2026.9 installer. Keep using the 2026.8 connector for publishes around 200 MB; upload larger NWC and NWD files. See Navisworks in 2026.9.

FAQ

The model was published from a connector that has already updated to 2026.9 — Revit, Archicad, or any other design tool once it updates. Vectorworks’ current read path doesn’t support that format yet. No 2026.8-or-earlier connector can load data published by a 2026.9-or-newer connector, so this isn’t specific to Vectorworks. Ask the publisher to use a 2026.8 connector build until Vectorworks ships its own 2026.9 read-side update — download it from releases.speckle.systems.
