Revit Plugin

The Algomim Revit plugin lets you control Revit through natural language. Create elements, modify parameters, apply view filters, generate schedules, and more — all from the Algomim chat interface.

​
Supported Versions

  • Autodesk Revit 2024
  • Autodesk Revit 2025
  • Autodesk Revit 2026

​
Installation

1

Download the installer

Download the Revit plugin installer from the Settings page in chat.algomim.com.
2

Close Revit

Make sure Revit is completely closed before installing.
3

Run the installer

Double-click the downloaded .exe file and follow the setup wizard. The installer automatically detects which Revit versions you have installed.
4

Start Revit

Launch Revit. You should see an Algomim tab in the ribbon.
The installer places plugin files in your %AppData%\Autodesk\Revit\Addins\ folder for each detected Revit version.

​
Connecting to Algomim

1

Open a project

Open a Revit project (or create a new one).
2

Go to the Algomim tab

Click the Algomim tab in the Revit ribbon.
3

Click Connect

Click the Connect button. A dialog will appear asking for a PIN.
4

Get your PIN

In the Algomim web app, start a new chat and click the Connect button (plug icon). Copy the 6-digit PIN.
5

What You Can Do

The AI has access to the full Revit API through the execute_script tool. Common operations include:

​
Element Creation & Modification

  • Create walls, floors, roofs, ceilings, and columns
  • Place family instances (doors, windows, furniture)
  • Set and modify element parameters
  • Move, copy, rotate, and delete elements

​
Views & Visualization

  • Create plan, section, 3D, and sheet views
  • Apply view filters and override graphics
  • Color-code elements by parameter values
  • Export images from views

​
Schedules & Data

  • Create and configure schedules
  • Query element data and counts
  • Check parameter values across the model

​
Families & Types

  • Duplicate and modify family types
  • Edit compound structures (wall/floor/roof layers)
  • Search the Revit API for available classes and methods
For Revit-specific prompting tips and example commands, see Revit Best Practices.

​
Script Context

When the AI writes C# scripts for Revit, it has access to these context variables:
VariableTypeDescription
docDocumentThe active Revit document
uidocUIDocumentThe UI document for selection and views
activeViewViewThe currently active view
uiAppUIApplicationThe Revit UI application
Scripts run inside a transaction, so changes can be undone with a single Ctrl+Z.

​
Troubleshooting

  • Verify the plugin is installed: check %AppData%\Autodesk\Revit\Addins\{version}\ for Algomim files
  • Restart Revit after installation
  • Check that your Revit version is supported (2024, 2025, or 2026)
  • Make sure you have an internet connection
  • Check that the PIN hasn’t expired (PINs are valid for 5 minutes)
  • Try generating a new PIN
  • Verify your firewall isn’t blocking outbound WebSocket connections
  • The AI may need more context — try describing your request more specifically
  • Check the Revit status bar for error messages
  • Make sure you have an active view open (not just the Start page)

​
Updating the Plugin

When a new version is available, download the latest installer from the Settings page and run it. The installer will automatically replace the old version.
