Flux vs Adam CAD: An AI mechanical engineer, expanded to the complete device.

Adam works in the CAD, PLM, and simulation tools that your team already licenses. Flux has the hardware tools built in, so the AI engineer designs the board, the mechanical parts, and the firmware in one live project.

Flux editor: the AI engineer plans and delegates tasks while the 3D view shows the complete device: enclosure, circuit board, and wiring

What Flux and Adam are

What Flux is

Flux is your team's autonomous hardware engineer. Give it a requirement. It plans the design, picks the parts, draws the schematic, routes the board, designs the mechanical parts, and writes the firmware. It checks its own work in simulation and design rule checks, and hands your engineers files ready to manufacture.

What Adam is

Adam is an AI mechanical engineer and CAD copilot from Adam AI Labs. It works in your CAD, PLM, and simulation tools and hands back finished work.[1]

Adam has a Free plan, Pro and Max plans for individual engineers, and Team and Enterprise plans for hardware organizations.[2]

What Adam does

Works in your CAD

Adam connects to CAD tools such as Onshape, Autodesk Fusion, and SOLIDWORKS, and to PLM systems such as Arena.[3]

Prompt to CAD and drawings

Adam generates designs from a prompt and creates 2D engineering drawings from 3D CAD models.[1]

Simulation and DFM loop

Adam connects simulation software to your CAD, carries the results back into the design, and checks a design for manufacturability.[1]

How Flux is different

Adam works through the CAD, PLM, and simulation tools that you connect, and each of those tools needs its own license. Flux has the tools built in: a CAD and EDA editor, simulation, design rule checks, 734,000+ public parts with live distributor data, and manufacturing files. The Flux AI engineer designs the board, the mechanical parts around it, and the firmware, in one live project in your browser. Everything is included in your Flux plan.

Mechanical design, done by the AI engineer.

Parts and assemblies

Flux designs single parts and complete assemblies, from a bracket or an enclosure to a complete robot arm. It brings every part together in one model.

Fits the real board

Flux fits each part to the real board: its mounting holes, connectors, and cutouts. The agent can change the board and the mechanical parts together.

One parts library

Chips and connectors, devices that are not on the board, and mechanical hardware such as screws and standoffs are in one library for the whole product.

Editable CAD code

Flux saves each part as a STEP file and as editable CAD code. Your engineers can review the code and change it.

Move your CAD work to Flux.

Load your mechanical parts. Tell Flux in plain words how to change them. Then have the parts made.

The request, as typed in Flux

“The holder must cover a much taller power supply. Make the bent side flange 40 mm deeper. Keep the 4.4 mm hole in the flange where it is. Then cut five 5 x 30 mm vertical vent slots in the new part of the flange, 15 mm apart and centered on the flange width.”

Before: the STEP file from Autodesk Inventor. The bent flange is 24.5 mm deep.

Bring your existing work

Import complete projects, part libraries, and 3D models. Schematics, parts, and placement come across, and routing from most formats.

Keep going with your AI engineer

Imported designs are ready to edit right away. Ask "move the USB cutout 3 cm left" or "make the enclosure tighter", and Flux does the work.

Get it manufactured

Flux hands you the files that your manufacturer needs: Gerber, ODB++, IPC-2581, bill of materials, and pick-and-place for the board, and STEP, STL, or 3MF for the mechanical parts.

Kernel-agnostic CAD

Builds every part on the right CAD kernel.

Traditional CAD tools are locked to one geometry kernel, and every part inherits its limits. Flux is kernel agnostic, the same way it is model agnostic. The AI engineer picks the right kernel for each part, switches kernels when one cannot build a feature, and brings every part together in one model.

  • OpenCascade

    Exact, standard geometry that CAM and other CAD tools read cleanly. Strong for machined parts and multi-part assemblies.

  • SMLib

    Smooth, curvature-continuous surfaces for hand-held and consumer products.

  • Parasolid On request

    The kernel inside SolidWorks, NX, Solid Edge, and Onshape, for native-quality exchange with those tools.

Curvature combs on an enclosure in the Flux 3D view
1. Shape the enclosure. NVIDIA SMLib builds the curved edges of the front enclosure. Curvature combs show how each curve bends, so you see where the surface flows and where it breaks.

2. Check the board inside. Flux cuts the same enclosure in half. You see the board, the displays and the knob inside, and you check each clearance before you print.

Surface quality you can see. Zebra stripes, curvature maps, and curvature combs show that every surface is smooth before the part goes to tooling.

Verification lab

Simulates and checks its own work before you build.

Flux doesn't stop at generating designs. The AI engineer simulates and checks its own work with professional-grade solvers, and it shows you the results.

Mechanical simulation

Finite-element stress analysis of brackets, enclosures, and mounts.

Thermal simulation

Flux runs PCB thermal analysis of the routed board at stated operating powers, plus heat and airflow simulation of the enclosure, before you build.

Fluid simulation

Airflow and cooling through the enclosure, so vents, fans, and heat sinks work before the first prototype.

Circuit simulation

SPICE simulation of analog, power, and mixed-signal circuits, with Monte Carlo, temperature sweep, and noise analysis, run and read by the AI engineer.

Electromagnetic simulation

Full-wave simulation of the routed board: signal integrity, power integrity, impedance, S-parameters, crosstalk, and antennas.

Design rule checks

Electrical and manufacturing rule checks on every schematic and board.

Datasheet checks

Reads the datasheet of every part and checks the design against its pinouts, ratings, and limits.

Manufacturing

Gets quotes from your fabricators as the design changes.

Flux gets quotes directly from the fabricators for circuit boards and assembly, 3D printing in plastic and metal, CNC machining, sheet metal, laser cutting, injection molding, casting, and wiring harnesses. The AI engineer compares price and lead time, checks the design against each fabricator's rules, keeps the quote current as the design changes, and places the order when you confirm.

Why teams choose an AI hardware engineer

The whole device, not one part

An AI CAD tool makes mechanical parts. Flux designs the board, the mechanical parts, the firmware, and the wire harnesses in one project. It fits each part to the real board: its mounting holes, connectors, and cutouts.

Nothing else to buy

Flux does not need a desktop CAD license to work. The CAD and EDA editor, the parts data, simulation, and manufacturing files are built in and included in your plan. Flux runs in your browser.

Checks its own work

Flux runs stress, thermal, and airflow simulation on the parts that it designs. It runs circuit and electromagnetic simulation and design rule checks on the board.

Gets the parts made

Flux gets quotes for 3D printing, CNC machining, sheet metal, and laser cutting, and for boards and wire harnesses, from the project.

Parts you can buy

Chips, connectors, and mechanical hardware such as screws and standoffs are in one library of 734,000+ public parts, with live prices and stock from distributors.

One live project for the team

Electrical, layout, mechanical, and firmware engineers work in the same live project with the AI engineer. Share a project with a link.

One platform

And the electronics and firmware too.

Flux is not a collection of disconnected CAD applications. It is one AI-native engineering platform where every discipline shares the same project, the same data, and the same AI engineer.
