Alpha · walls first, more building systems next

Know what you're building before you build it.

The biggest decisions get made before the details exist. Axo models the details in Revit first, starting with every layer of the wall, so you decide with the full picture.

Placeholder

A real, unedited Axo session goes here: the request to the assistant, the plan Axo returns, and the approval in Revit.

It will be captured from a live session and scrubbed of ids, paths and emails before it is published.

How it works

You ask. Axo plans. You approve.

Axo connects the assistant you already use to your open Revit model, through a Revit add-in and a remote MCP server.

  1. Connect

    Install the Axo add-in for Revit and add Axo to your AI assistant as an MCP server.

  2. Ask

    Tell your assistant which walls to build out. Axo reads them from your open model, with their types and openings.

  3. Review the plan

    Axo plans the framing and every layer from rules, not guesses, with quantities for each layer. Nothing in the model changes yet.

  4. Apply

    Axo places the work as native Revit elements. In Confirm mode, each write waits for your approval in Revit.

Walls first

Every layer of the wall, as its own element.

A wall type in Revit is one element. Axo builds what is inside it: the framing and each layer, as elements you can select, schedule and edit.

  1. Cladding

    The outer finish that sheds the weather.

  2. Membrane

    The weather-resistive barrier behind the cladding.

  3. Sheathing

    Panels fixed to the framing that brace the wall and carry the membrane.

  4. Framing

    Studs, plates and headers, laid out around the openings.

  5. Insulation

    Fills the cavities between the studs.

  6. Gypsum board

    The interior lining.

A typical exterior wall, outside to inside. Your wall type sets the real layers, materials and thicknesses.

Walls are the first building system Axo models, and more will follow. Things will change and some will break. Tell us when they do.
