What Autodesk Assistant can do in 2027 depends on which application you open. In Revit 2027 it answers product questions, queries the model and changes it, and Autodesk's November updates widened what it can change. In AutoCAD 2027 it works with drawing data and standards, and the 2027.1 update made its queries considerably more useful. In Revit 2023 through 2026 it isn't available at all. This guide follows Autodesk's documentation as of November 13, 2026, and what you see can depend on which updates you have installed.
Autodesk Assistant Revit AutoCAD 2027 capabilities
Autodesk documents three kinds of work for Revit Assistant: contextual help about Revit itself, queries about the open model, and changes to that model. See the Revit Assistant documentation. AutoCAD's Assistant is described differently. Its documentation focuses on working with drawing data and on standards-related help, and the AutoCAD 2027.1 update notes list improvements to queries and to its awareness of the current selection.
The two share a name, so it's easy to watch a Revit demo and assume AutoCAD does the same thing, or the other way round. They're better treated as separate tools, and the sections below take each in turn.
Revit 2027.3 and 2027.4: schedules, graphics and traceability
Autodesk's November 10 announcement of Revit 2027.3 and 2027.4 describes more schedule and graphics operations in Revit Assistant. Since 2027.2, Assistant's service updates have arrived separately from Revit point releases, so what you can do depends on the Assistant service as well as your installed Revit update. These operations move it further into documentation work, which takes up much of a project's hours. The same updates improve traceability of the changes the assistant makes. Once an assistant is editing a shared model, you need to see what it changed before the model goes out, especially when one request touches many elements.
The updates also introduce DynamoMCP. With Dynamo 4.2.1 in Revit 2027.3, the assistant can build Dynamo graphs and run them, and Revit 2027.4 with Dynamo 4.2.2 adds batch runs and better graph management. A graph is a different kind of result from a direct edit. It's a visual script your team can open, read, adjust and run again on the next project, so the logic behind a change stays visible and reusable.
If you've read that Revit's AI tools are limited to help questions or are read-only, that description is out of date.
The Revit MCP add-ons are a separate route
The same announcement describes Revit public MCP add-ons, released as a Technical Preview with Read, Write and Experimental extensions. MCP, the Model Context Protocol, is an open standard that lets an AI client running outside Revit, such as a desktop chat app, call tools inside Revit. This sits apart from the Assistant panel built into the application. You bring the AI client, and the add-on defines what that client can reach in the model.
The extension names show how access is divided. Read gives an external client access to model information, Write lets it make changes, and Experimental, as the name suggests, holds tools that are less settled. Because this is a Technical Preview, expect the tools and their behavior to change between updates.
When someone shows you AI working in Revit, it's worth asking which route you're looking at: the built-in Assistant or an external client connected through MCP. The setup, accounts and permissions differ. Our AutoCAD MCP guide covers how the connection route works on the AutoCAD side.
AutoCAD 2027.1: counts, selections and clearer reports
AutoCAD's Assistant got its most practical improvements in 2027.1. According to the release notes, it can now count objects, analyze what you've currently selected, report results with explicit units, and handle broader questions about text, layers, attributes and closed polylines.
In day-to-day drafting, these are questions you'd otherwise answer with a quick select filter, a data extraction or a lot of clicking. Examples include how many of a given block sit in the selection, which layers the selected objects are on, what attribute values a set of tags carries, and details of the closed polylines in a room layout. Explicit units fix a small but real problem: an area reported as a bare number is easy to misread when you can't tell whether the drawing was set up in millimeters or feet.
Selection awareness also makes the answers easier to check. Select the objects first, ask about them, and compare the reply with what's highlighted on screen.
Keep its scope in mind. The documentation describes drawing-data queries and standards-related help, and these notes don't describe general geometry editing. If your task needs objects changed, look for that specific operation in Autodesk's current documentation before planning around it.
If you're on Revit 2023 through 2026
Autodesk's version availability guidance says the built-in Revit Assistant is available in Revit 2027 and later. A project in Revit 2023, 2024, 2025 or 2026 won't show the panel, whatever settings you change. Moving a live, coordinated project to a new release just to get an assistant is a big decision for any team.
ArchiLabs Desktop supports native model editing in Revit 2023, 2024, 2025, 2026 and 2027, so the same tool works on older projects and current ones. It runs on Windows and works with native Revit and AutoCAD files. You can attach PDFs, spreadsheets, marked-up screenshots or selected elements to a request, which helps when a revision begins as a markup or a changed specification. Desktop starts at $19 a month plus usage credits (pricing). Try Desktop on a project in the release you're using now.
