Mechanical engineering
Your next part, calculated and scripted
You lead the design, so you're the CEO. StellarFirm gives you AI Agents, Agentic Assistants for your work. The Mechanical Engineer turns your requirements into checked calculations, an editable parametric model with STEP and STL files, a dimensioned drawing, and a bill of materials, all in one revision, while the Scientist assistant checks the numbers independently. Every check that ran is recorded, and a check that did not run is never reported as passed. Nothing here is a drawing for manufacture until a qualified engineer has checked it. You give the final go.
From brief to concept
A concept part for an engineer to review
- The part, the load, and the requirements
- The model, the checks, and the drawing
- Where a qualified engineer checks the result
Nothing is sent or shipped unless you asked for it or approved it, and money always asks.
The Mechanical Engineer makes the model, the drawing, and the checks. The Scientist assistant checks the numbers. Supplier mail and anything that leaves wait for your Approve.

Illustrated workflow
02 / The team works
The team works
The assistants take the goal, use the ready prompts and skills, and do the work in the tools you connected.
How it works
From a goal to a result.
- 01
Set a goal
You say what done looks like: a ticket, a client, a deadline, or a draft.
- 02
The team works
The assistants take the goal, use the ready prompts and skills, and do the work in the tools you connected.
- 03
You approve the risky step
Anything that sends, publishes, ships, or charges waits for your Approve. Approve a kind of step once and that assistant remembers it, but money always asks. You are the CEO.
- 04
You get the result
A revision with the editable source, STEP and STL files, a dimensioned drawing, a bill of materials, and the checks that ran, ready for a qualified engineer and your final go.
Example
Send the revision notes to your supplier
It sends to people, so it asks first.
The team
You, and the assistants.
You, the CEO
You set the requirements, choose between the options, and approve what leaves the desk, such as a message to a supplier.
Mechanical Engineer
Turns your requirements into checked calculations with units, parametric CadQuery models with STEP and STL exports, dimensioned drawings, and a bill of materials. It runs the checks on its own computer, records what ran, and hands over one revision: the editable source, the exports, the drawing, the checks, and a manifest.
Scientist assistant
Checks the calculations and the evidence independently: the units, the limiting cases, how the design can fail, and what a prototype test really shows. Every value traces back to a standard or datasheet you give.
Product owner
Keeps the requirements, the milestones, and the acceptance criteria, and names the revision on each task.
Coder
Codes the firmware, the control software, or the storefront with you from the approved interface brief, writes the tests, and opens the pull request on its own. A merge or a deploy waits for your Approve.
Integrations
The tools it starts with.
- Onshape
- GitHub

Built in
What your assistants can use.
Checked CAD in one revision
The Mechanical Engineer writes editable CadQuery and exports STEP and STL files, with a dimensioned drawing, a bill of materials and the checks that ran.
Its own computer
Each assistant works on its own computer in StellarFirm cloud, set up with the tools its job needs, and hands you the files.
Assistants ask each other
An assistant can ask a teammate a question and pass it notes and files, all inside StellarFirm. A teammate's note never skips an Approve.
Pages and documents beside the chat
A page, chart, table, document or picture an assistant makes opens beside the chat, so you can check it while the work goes on.
Long jobs in the background
A big job starts at once and runs in pieces in the background, streaming back as it goes. You can stop it any time, and sends and spending still ask.
Research tools
Web, news and scholar searches, scholarly works, video transcripts and market data, all read-only.
Everything it makes, in one Library
Every page, document, app and file your assistants make is kept in one Library. You file them by topic and kind, and the Library never deletes a file.
Roles you make yourself
Name a role we don't ship, say what it does and give it any of our skills or your own. Comes with Ultra and enterprise.
