Four Revit add-ins and tools announced updates between November 12 and 13, 2026. None is a major launch on its own, but they cover urban context, quantity take-off, clash resolution and file compatibility. Here is what changed and what to check.
What’s new
VU.CITY Revit plugin: Revit 2027 support. VU.CITY updated its plugin, which sends Revit models to its urban digital twin platform, on November 12. The new version supports Revit 2027, adds GLB export for the new VU.CITY platform and refreshes the export interface. VU.CITY recommends installing through its Auto Update Service, warning that outdated versions may cause export errors.
AgileBOQ: free Revit add-in for bills of quantities. AgileBOQ now lists a free add-in for Revit 2025 and 2026 on Windows. It adds an AgileBOQ tab with a “Send to AgileBOQ” button that saves the model as IFC with quantities and rooms, then opens it in AgileBOQ in the browser for measurement to NRM and pricing. The company says nothing is uploaded: the file is shared only on your own computer for 45 minutes. Revit 2027 is not listed yet, and the page gives no price for the AgileBOQ application itself.
ClashFree: public beta for AI clash resolution. ClashFree announced on LinkedIn on November 12 a public beta of its Revit add-in for MEP clashes. Per the announcement, it imports a Navisworks or BCF clash report, groups clashes by cause and lets an AI propose and build the MEP fix, which the user approves as a single undo step, with the model kept local. We could not verify these details on an official product page, so treat them as the vendor’s claims.
Revit Downgrade: engine update. Revit Downgrade is a free web tool by independent developer Phan Cong Vu Duc that converts .rvt, .rte, .rfa and .rft files from Revit 2023 to 2027 down to Revit 2022. In a LinkedIn post on November 12, the author reported a major engine update with 3 failures out of 272 test files. The site states that elements the older version does not know are removed (with a CSV list of removed ElementIds), files are capped at 1 GB and deleted after two hours, and the tool is not affiliated with Autodesk.
Why it matters
- VU.CITY users who moved to Revit 2027 can now export without staying on an older Revit.
- AgileBOQ gives cost consultants a free route from Revit to a priced BoQ, but only on 2025 and 2026 for now.
- ClashFree is in beta: test it on a copy of the model and review every proposed fix.
- Downgrading is lossy by design. Use it to share geometry with a partner on an older version, never as a round trip for your working model, and check confidentiality rules before uploading project files to a third-party server.
