PRIVATE BETAFusion 360 & SOLIDWORKS

Agentic CAD,

on demand.

BlobCad is an AI-native CAD design agency. Our agent models parts natively inside your Fusion 360 or SOLIDWORKS session — and when a job outruns it, a human CAD expert takes over and finishes the file.

Why BlobCad

Software when it works. Humans when it doesn’t.

Every other AI CAD tool hands you a frozen triangle soup, then leaves you alone when it stalls. BlobCad writes parametric feature trees inside your own CAD — and staffs the jobs the agent can’t close.

Core features

Built for real engineering.

Kernel

Native kernel execution

No mesh approximation anywhere in the pipeline. BlobCad drives the Parasolid and ShapeManager kernels directly, building sketches, constraints and extrusions as first-class modelling operations inside your desktop session.

Interop

One agent, both CAD systems

Autodesk Fusion 360 and Dassault SOLIDWORKS, from a single reasoning engine addressing local MCP endpoints. Your files, your licences, your machine — BlobCad never asks you to move work into someone else’s tool.

Integrity

Feature trees that survive contact

Every generated model keeps an editable sketch tree and named dimension parameters. Fillet it, shell it, drive it from a spreadsheet, or run stress analysis on it — the geometry behaves exactly as if you had drawn it yourself.

Handoff

A CAD expert when the agent stalls

Hard parts do not become your problem. One click hands the job — with the live .f3d and its full feature tree — to a vetted CAD expert who finishes it in the same file and sends it back. You get a finished part either way, which is what makes this a service rather than a tool.

How it works

From prompt to finished part.

BlobCad attaches to the CAD session already running on your machine. No file exports, no format conversions, no round trips — and no dead ends, because a human expert can pick up any job the agent cannot close.

Prompt

Describe it in your live session

Ask for geometry, hand over a spec sheet, or request a change to an existing mounting pattern — inside the Fusion 360 or SOLIDWORKS document you already have open.

Execute

The agent drives the CAD kernel

BlobCad resolves your constraints and calls the kernel API directly over MCP — sketch planes, extrusions, fillets, patterns — as real modelling operations.

Iterate

Edit the tree like you drew it

A fully constrained parametric part with a readable feature tree. Change one dimension and everything downstream rebuilds. Ready for CAM, FEA and tolerance analysis.

Escalate

Hand the hard ones to a human

When a job outruns the agent, one click sends it — live file, full history — to a vetted CAD expert. They finish it in the same document and it comes back to you done.

AI + humans

When the AI gets stuck, a human takes over.

BlobCad is not just an AI tool — it is a CAD design service. The AI does most of the work, and a network of real CAD engineers is there for the parts it cannot finish. You always stay in control: nothing goes to a human until you say yes.

AI tries first

The AI models your part

You describe the part in plain English and the AI builds it inside your live Fusion 360 or SOLIDWORKS session. Most of the time, that is the whole job — done.

It flags the hard parts

BlobCad notices when it is stuck

When a part is too tricky and the AI cannot finish it, BlobCad tells you instead of guessing. It offers to hand the job to a human — you never have to ask.

A human finishes it

A real CAD expert takes over

You approve the job and a CAD engineer picks it up from the job board. They finish the part and it lands back in your file — same editable feature tree, ready to use.

I tried this a few times and could not get a clean, mating thread. This one is better handled by a person.

Pricing

Software you rent. Experts you call.

The agent is a subscription. Human expert time is billed per job, quoted before you accept. Beta users keep founding rates for as long as their subscription stays active.
