Assistant sign-in has been updated to support both Microsoft accounts and AEC Portal accounts. This makes it possible for users that cannot or will not grant admin consent to Assistant cloud services to get access through a new account in the AEC system.
The login flow is also more stable, which makes automations dependent on Assistant Cloud more reliable.
This release adds support for using AI Chat together with Revit. When Assistant is connected to Revit, AI Chat connects as well.
You can now use AI Chat not only to ask questions about the active Revit model, but also to help make changes in it. This gives users a new way to inspect the current document, work with model elements, and carry out model-related tasks using natural language.
Connecting to a new integation from Assistant is now reflected immediately across all tools, including the AI chat.
The AI troubleshooting panel now appears immediately when you click "Ask AI" and shows a loading indicator while it analyses the error, so you know something is happening. Task results (text and markdown) now display alongside the AI suggestion in a side-by-side layout instead of stacking vertically, giving more room to read both. Error detail dialogs are wider, better styled, and renamed to "Error details" for clearer language. Popping a task result out into its own window is also smoother, with no visual flicker.
The Dynamo extension installer now automatically detects every Revit and Dynamo version already on your machine and installs the closest compatible package for each one. You no longer need to match a hardcoded supported-version list, and edge cases such as intermediate minor versions or enterprise folder overrides are handled gracefully.
Some extensions could feel cluttered when too many fields were shown at once, and older saved actions could stop behaving as expected after an extension had been updated.
Extension forms can now respond more clearly to what you select. Fields can appear, hide, or be disabled only when they matter, which makes forms easier to follow. Saved actions also handle extension updates better, especially when the form layout has changed.
Some users experienced an issue where filter controls in Assistant could open duplicate popup windows that behaved as if they were linked together.
Filter popups now open the way you would expect, so filtering is easier to use and easier to trust.
Some Try/Catch task flows in Assistant could report a run as failed even when the recovery step had handled the problem and the workflow could continue.
Results now describe these runs more accurately. If the main step fails or times out, but the follow-up recovery step works, the run can now be shown as a partial success instead of a full failure.
Some users experienced slow model opening and limited control over linked content when opening cloud-based Revit models.
Opening cloud-based Revit models is now faster, especially when worksets and linked files affect startup time. You can also choose options such as "Do not load Revit links" and "Do not load IFC links." That makes it easier to open a model in a lighter state when you do not need all linked content right away.
When too many integrations were started at the same time, users could experience long waits and confusing timeout-style error messages before the tool reported that the maximum parallel limit had been reached.
Assistant now handle this situation more clearly. When the maximum number of parallel integrations has been reached, the message is clearer and the tool avoids unnecessary timeout-style failures while waiting for a free slot.
This release adds support for Navisworks 2026.
Tools Installer now checks for and offers to install patch and minor updates, not only major releases. You'll be prompted to update as soon as a new fix or improvement is published, instead of waiting for the next major version.
