Describe a part. Get an editable model in Fusion.
MeshAI is an AI add-in for Autodesk Fusion. Give it a sentence, a sketch or a drawing, and it builds a parametric model you can keep editing. Next, it carries that model into meshing and simulation.

From your request to the Fusion timeline
Describe or upload
Type the part, or attach a sketch, photo, PDF, DXF or SVG.
Claude writes the script
A Fusion API script that takes account of what’s already in your design.
It runs in Fusion
The model appears in your timeline, with key dimensions set up as user parameters.
Errors get another try
If the script fails, Claude reads the error and tries again, up to twice.
Follows the workspace you’re in
The mode follows your current tab, or you can set it to Auto and let Claude choose.
| Mode | What it builds | Example request |
|---|---|---|
| Solid | Extrudes, revolves, lofts, holes, shells and patterns | 60×40×10 mm plate, four M5 holes |
| Sheet Metal | Bent parts from the active sheet metal rule. Where the API can’t make a flange, it builds the solid and tells you to run Convert to Sheet Metal. | 1.5 mm steel L-bracket, 50×30 mm legs |
| Surface | Surface loft, sweep, patch, trim, stitch and thicken | Wavy roof surface 200×100 mm |
| Sketch | Constrained 2D geometry with parameter-driven dimensions | Fully constrained 40×8 mm slot |
| Mesh | Mesh bodies from math, or a mesh of a solid | Low-poly sphere, 30 mm |
| Assembly | Bottom-up components, positions and joints | Hinge: two leaves, a pin, revolute joint |
Bring a napkin sketch or a DXF
Photos, scans and PDFs
Claude reads the shapes, dimensions, notes and views, then builds the part. It lists any dimensions it had to assume, so you can check them.
DXF and SVG
These come in as a real Fusion sketch with exact geometry. Claude then extrudes and cuts from its profiles.
Prototype
Record how you build a part, then rerun it
Record your steps in Fusion and save them as a workflow. Run it later and ask for changes, such as different dimensions, and AI rebuilds the part. This is an early prototype that we’ve tried on simple sketch-and-extrude parts.
One path from model to solver
We’re extending MeshAI beyond CAD, starting with GiD. The engineer reviews every proposed command before it runs.
Build
MeshAI creates the parametric model in Fusion.
Send
One click exports STEP and design details to GiD.
Mesh
An assistant in GiD proposes cleanup and meshing commands.
Validate
AI checks measured mesh quality before solver time is spent.
Solve
Run the analysis in your own solver, and get AI help reading the results.
One AI across your engineering apps
STEP carries the geometry between apps, and each app gets a small connector. Here’s where each one stands.
| App | Stage | Status |
|---|---|---|
| Autodesk Fusion | CAD | Working today |
| GiD | Meshing, setup and results | In development |
| Onshape | CAD, in the cloud | Planned |
| SolidWorks | CAD, on Windows | Planned |
| Ansys | Meshing and solving | Planned |
| ParaView | Results | Planned |
Built around your own standards
Company standards
Use your design guides, material specs and preferred parts when generating models, with each part listing the rules it applied.
Check design
Review any open model for thin walls, edge distances, bend rules, hole sizes, hard-coded dimensions and naming.
How your data is handled today: each install uses your own Anthropic API key, which stays on that computer. Your requests, design details and any files you attach are sent to Anthropic’s API to generate the script. A company server with central keys and usage controls is planned.
Pilot it on your own parts
Send us your design guide and a few typical parts, and we’ll show you what MeshAI builds from them in Fusion.
