Autodesk released the Revit 2027.4 update on November 10, 2026, less than two months after 2027.3. It is available now through the Autodesk Access app or from your Autodesk account, and it cannot be uninstalled once applied.
What’s new
The headline changes sit on the Dynamo and Forma side rather than in core modeling tools.
- Dynamo Core 4.2.2. When Autodesk Assistant edits a graph, its changes are now batched so the graph runs once per batch instead of once per edit. DynamoMCP gains tools to read node values, switch run modes, find, group and collapse nodes, cancel runs and read Dynamo log lines.
- Graphs saved through Assistant keep their layout. Node positions, groups, notes and renamed nodes are preserved.
- Selective Forma conversion. A new Create from Selection option, with Sketch Area or Select Items, converts only the chosen terrain, buildings, parcels or roads into native Revit elements. Everything else stays as reference context.
- Daylight Potential in Revit. The Forma analysis now runs inside Revit next to wind and microclimate, with a colour-coded heatmap on the building shell.
- Smaller improvements. A faster Save as Cloud Model dialog with dark theme support, faster PDF insert for large page counts, an Insight Analyze workflow for workshared projects and Revit Home improvements.
According to the release summary published by reseller CAD Pilot, the update also fixes Autodesk Assistant going blank after Dynamo is closed, patches the FBX SDK for two CVEs, speeds up electrical circuit editing and resolves several crashes, including with linked-model room tags and OBJ or STL import.
Why it matters
If your team uses Autodesk Assistant with Dynamo, 2027.4 makes AI-driven graph editing faster and less disruptive. The partial Forma conversion is also a practical fix for anyone who brought site context into Revit and did not want every surrounding building converted.
Before rolling it out, keep two points in mind:
- The update cannot be uninstalled. Test it on one machine with your add-ins first.
- It needs access to the original install resources, which matters for offline or locked-down deployments.
