AI CAD Harness
Edits Autodesk Fusion 360 models agentically to clean up feature trees and generate CAD
Last verified:
What is AI CAD Harness?
AI CAD Harness — dam Fusion is an AI copilot add-in for Autodesk Fusion 360 that works inside the CAD app rather than exporting a separate black-box model. It reads your parts, understands the existing feature tree, and edits the model agentically so you can keep full visibility and control over the design history.
The website positions it as a CAD harness for real mechanical workflows, not just prompt-to-3D generation. Examples on the site include merging redundant features, cleaning up unreadable trees, renaming features, adding fillets, parametrizing models, and generating CAD end-to-end.
It is designed to live natively inside Fusion 360, with the Adam palette docking on the right after sign-in. The install page emphasizes a fast setup path, with a one-line installer for macOS and Windows, plus a manual bundle installation option for users who prefer that route.
The product is aimed at mechanical engineers and CAD users who want AI help without giving up direct control of the feature tree. It also appears to be in beta and part of a broader effort to integrate across CAD tools, but this install page is specifically focused on Fusion 360.
AI CAD Harness pricing
Pricing model: Freemium
The install page does not list any pricing, free tier, or paid plan details. It only provides installation instructions for Adam Fusion, including a one-line installer for macOS and Windows and a manual bundle download/install path. It also says the add-in loads inside Fusion after you enable it and sign in with your Autodesk account.

Frequently asked questions about AI CAD Harness
What is Adam Fusion?
Adam Fusion is an AI copilot add-in for Autodesk Fusion 360. It works inside Fusion to read your parts, understand the existing feature tree, and make edits agentically while preserving visibility into the model history.
How do I install it on macOS?
The page offers a one-line terminal install command for macOS: curl -sSL https://fusion.adam.new/install.sh | bash. After that, you quit Fusion, reopen it, open Shift+S, go to the Add-Ins tab, find AdamFusion, click Run, and optionally tick Run on Startup.
How do I install it on Windows?
The page offers a PowerShell one-liner for Windows: irm https://fusion.adam.new/install.ps1 | iex. After installation, you restart Fusion, open Shift+S, go to the Add-Ins tab, find AdamFusion, click Run, and tick Run on Startup if you want it to load automatically.
Can I install it manually instead of using a script?
Yes. The site provides a manual path where you download AdamFusion.bundle.zip, unzip it, move the Contents folder into Fusion’s AddIns directory, rename it AdamFusion, then restart Fusion and enable the add-in from the Add-Ins panel.
Why do I need to restart Fusion after installing?
Fusion add-ins load at startup, so the page instructs users to quit and reopen Fusion after copying or installing the bundle. It specifically notes that a hard quit is required on macOS, not just closing the window.
Why doesn’t it appear immediately after installation?
The website says Fusion ships new add-ins disabled until you click Run once. You need to open the Add-Ins panel with Shift+S, find AdamFusion, run it, and then it can be set to Run on Startup.
What kinds of tasks is it meant for?
The site highlights tasks like merging redundant features, renaming features to make the tree readable, rounding internal edges with a 2 mm fillet, parametrizing models, and generating CAD end-to-end. The emphasis is on practical in-CAD editing rather than just generating an exported file.
Does it work as a black-box STL generator?
No, the page explicitly frames it as the opposite of a black-box STL workflow. It is meant to operate directly on the feature tree inside Fusion so engineers can see, control, and modify the design history.
Who is it for?
It is aimed at mechanical engineers and Fusion 360 users who want AI assistance inside their CAD workflow. The design of the product suggests it is especially useful for people who care about feature trees, parametrization, and editable CAD history.
What does the interface look like after installation?
According to the page, the Adam palette docks on the right side of Fusion after you sign in with your Autodesk account. From there, you can start chatting and use the add-in inside the CAD environment.
