CAD as code · in private development

From idea to manufacturing, with your agent.

Describe what you need. The agent designs it as code, checks every fit, motion and load in numbers, and hands you the files to build it. You see the same model and decide.

KLIV, a walking robot built in KUTA CAD, waving. Cropped from a screen recording of Motion in the app.

One package, three ways in

Whatever you build, the same tools check it.

A bracket for the garage, a walking robot for the lab, a machine with a CE mark. The agent, the app and the checks are the same; what you need from them is not.

Makers

Print it, cut it, build it.

Parts that print without supports, in the orientation they print in
Sketch on a face or add a fillet by hand: the code follows
Laser and router sheets nested, a BOM and instructions
The enclosure's circuit board, out to KiCad and back

For makers →

Research

The robot you print is the robot you simulate.

MuJoCo, MJX and URDF from the CAD, rebuilt with every change
Every joint swept, torque per servo, mass as printed
The live twin, LeRobot datasets, training runs and deploy
Motion scripts checked frame by frame, filmed by the agent

Professional

Calculations you can sign, records you can audit.

VDI 2230, ISO 281, DIN 743 and the Eurocodes, validated against the standards' tables
A calculation report to check and sign, in your firm's look
PDM built in: items, revisions, documents, change orders, an audit log
Risk register, Machinery Regulation and the technical file

How it works

From a sentence to a part you can make.

Describe it
In your words, with a sketch, a photo or a STEP of what it must fit.
The agent models it
As build123d code in your repository. Every change is a version.
KUTA CAD checks it
Fits, joint ranges, strength and standards, in numbers. A failure names the part and the line.
You decide
Click a face to comment. Accept or reject each change in 3D.
Plan how it is made
Nested sheets, print plates, bend order, CNC setups, the mould.
Make it
Drawings, cut files, a bill of materials and instructions, in one package.

Watch a run

A desk lamp, from a brief to print files.

Recorded as it happened. The person comments; the agent proposes a change, its checks catch the clash it caused, and it fixes that too.

84 seconds, cut from three hours of recording. The agent's work is sped up the most: its first 76 minutes of modelling take 14 seconds.

The app

The same scene, in your browser.

You and the agent on one model, at the same time. Design, Motion, Simulate and Make along the top, the model tree on the left, the agent on the right.

The agent

Writes the model as code, in your repository.
Measures, sweeps joints and simulates, in numbers.
Builds each fix in a copy, for you to see first.
Asks when a choice is yours, with pictures to pick from.

You

Click a face: the agent gets the part and the line of code.
Sketch on a face, add a fillet: it is written into the code.
Drag a slider or change a hole: the code follows.
Accept or reject each change, with a 3D diff.

Provenance

Every face knows the line that made it.

Click a face and KUTA CAD traces it to the line of code that cut it. The agent edits the right line the first time.

# parts.py
def bracket():
    base = Box(P.BASE_L, P.BASE_W, P.BASE_T)
    upright = Pos(P.UP_X, 0, P.UP_H / 2) * Box(P.UP_T, P.BASE_W, P.UP_H)
    part = base + upright
    part = fillet(part.edges().filter_by(Axis.Y).group_by(Axis.Z)[1], P.FILLET_R)
    part -= Pos(P.UP_X, 0, P.PIVOT_Z) * Cylinder(P.BORE / 2, P.BASE_W, rotation=(90, 0, 0))
    return part

Why

Measured, not guessed.

An agent that can only render pictures guesses at fits. One that can ask how large the clearance is gets an exact answer, and designs.

An agent with screenshots

Do the fingers hit each other or the servo anywhere in their travel?“There looks to be enough room.”
Will the stand tip back when you press the screen?“The base is wide enough to be stable.”
Is the mill stiff enough to cut?“The welded frame should be rigid enough.”
Can the servo hold the arm straight out?“The servo is rated for this kind of load.”

An agent with KUTA CAD

Do the fingers hit each other or the servo anywhere in their travel?0 collisions through the full travel; 11.2 mm to the servo at the closest
Will the stand tip back when you press the screen?5 N at the top edge: it holds 1.70 × at 60° and 1.30 × at 70°, 1.25 needed
Is the mill stiff enough to cut?500 N at the spindle moves it 0.034 mm in the worst pose; limit 0.05 mm
Can the servo hold the arm straight out?31.8 % of the shoulder servo's rating, in MuJoCo

Built with it

Real projects, not renders of ideas.

Two robots built over weeks by a person and an agent, a 7.5 m mill from a two-line brief, and a dozen products from one-paragraph briefs, each with its checks and files.
