Flux for enclosure design

Your board. Its enclosure. Designed by AI.

Flux designs the enclosure around the real board, checks every fit and clearance, and prepares the files to print, machine, or mold.

Edit the enclosure you have

Your housing files. Edited by AI.

Bring the housing from SOLIDWORKS, Fusion, or NX, or a STEP, IGES, or BREP file from any CAD tool. Ask for the change in plain words, for example "make it 8 mm taller and keep the mounting bosses in place". Flux changes the housing and saves a new STEP file and editable CAD code.

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.
Before: the STEP file from Autodesk Inventor. The bent flange is 24.5 mm deep.
After: the flange is 64.5 mm deep, with five 5 × 30 mm vent slots. The 4.4 mm hole did not move. Flux saves a new STEP file and editable CAD code.

Your file stays safe

The original file stays in the project, unchanged. Flux saves each edit as a new file.

Parametric by default

Flux builds the enclosure as editable CAD code. Change the wall thickness or the mounting-hole spacing and the enclosure follows.

Back to your CAD tool

Export the full assembly as STEP and continue the work in the tool your team uses.

Capabilities

The enclosure engineer your board deserves.

Designs the enclosure around the real board

Flux reads the board outline, mounting holes, connectors, and part heights. It puts supports on the mounting holes and openings where the connectors are.

Checks every fit and clearance

Interference, space for each cable, screwdriver access, and worst-case and RSS tolerance stack-ups from the board to the lid.

Packs the whole device

Boards, battery, display, speaker, and wiring in one assembly. Flux places each part and shapes the enclosure around them.

Finishes it in real materials

Name the material of each part, from anodized aluminum and brass to clear acrylic, glass, plywood, and carbon fiber, and see it in 3D.

Board and enclosure stay in step

Moves the opening when the connector moves

Move a connector or a mounting hole on the board, and Flux updates the enclosure to match. Change the enclosure, and Flux updates the board outline.

Rigid-flex in the enclosure

Folds the flex board into the housing

Flux folds a rigid-flex board at each flex joint and checks its fit around the enclosure and battery.

Workflow

From a board to an enclosure you can build, Flux does the work.

  1. Start from the board or a sketch

    Start from the board in your Flux project or an IDF board from your ECAD tool. Add a hand sketch, a photo, or a dimensioned drawing, and Flux matches its shape and dimensions.

  2. Design for the process

    Two-part shells with snap fits and a removable lid. Injection-molded housings with draft, ribs, bosses, and a parting line. Sheet-metal covers with a DXF flat pattern. Hinges with a set opening angle. Screws, threaded inserts, standoffs, and fans come from the part library.

  3. Verify

    Air flow through the vents and fan, heat through the enclosure wall, and stress on the shell, before the first prototype.

  4. Make it

    Flux checks the part against SLA, SLS/MJF, CNC, sheet metal, laser cutting, and injection molding limits. Export STEP, STL, and 3MF, make dimensioned drawings with GD&T, and get quotes from Craftcloud, JLC and PCBWay 3D printing, Shapeways, OSH Cut, and SendCutSend.

Model-agnostic AI

Your favorite AI models. Our engineering superpowers.

Flux pairs frontier AI models with a state-of-the-art agent harness built for CAD and EDA. The models bring reasoning. Flux brings the engineering tools, project context, and workflows that turn that reasoning into working hardware.

  • OpenAI
  • Anthropic
  • Google Gemini
  • More as they ship
Adaptive model selection

Frontier performance at 30% lower cost.

Adaptive splits every engineering job into tasks and gives each task to the model that does it best for the price. Hard design decisions go to frontier models. Routine work goes to fast, low-cost models. Independent tasks run in parallel, so complete devices come together faster. Your team works with one AI engineer, and Flux handles the delegation behind the scenes.

Every frontier model, one platform

Work with the frontier models your team already trusts, inside Flux.

Engineering superpowers built in

Every model gets Flux's specialized engineering tools, project context, and workflows.

Upgrade without migrating

When a better model ships, your team gets it without switching engineering platforms.

No single-vendor lock-in

Avoid depending on any one model provider for your engineering capacity.

The right model for every step

Adaptive matches each engineering step to the model that does it best, from deep design decisions to routine checks.

Interoperability

Connect once. Work with the tools your team already uses.

Your standards

Write them once, every AI engineer applies them

One platform

One AI engineer. Every engineering discipline.

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.

  1. Boards, enclosure, and mounts in one model

    Mechanical design

    Parametric enclosures, brackets, and mounts, fitted to the real board's mounting holes and connectors. Bring in your own STEP models. One parts library for the whole product: chips and connectors, devices that are not on the board, and mechanical hardware such as screws and standoffs.

  2. USB-C power input schematic in Flux

    Electrical engineering

    Requirements, part research, schematic capture, and simulation.

  3. STM32 current-loop firmware that Flux wrote and compiled, in a syntax-highlighted code block

    Firmware

    Firmware for the board Flux designed, for example on Arm Cortex-M, RISC-V, AVR, or Pico, then built, analyzed, and unit tested.

  4. Bill of materials with stock and pricing

    Manufacturing

    Live sourcing, cost, quotes for boards, parts, and cables, and manufacturer-ready outputs.

Collaboration

Your team, your partners, and your AI engineers in one live project.

Flux runs in the browser. Everyone opens the same project, sees the same live design, and works on it at the same time. No files to send back and forth.

  • Edit together in real time.

    Engineers, reviewers, and AI engineers work in the same project at the same time. You see who is in the project and what they have selected.

  • Every change is saved.

    Flux records each change, who made it, and when. Open any earlier version, or restore it as a new project.

  • One shared space for your organization.

    Your organization's projects, parts, and design standards live in one place. Give the whole organization view, comment, or edit access.

  • Work with suppliers, clients, and contractors.

    Invite anyone to one project by email, with view, comment, or edit access. They get that project, not the rest of your organization.

  • Review where the design is.

    Comment in the project and @mention a teammate. The discussion stays with the design.

  • Try ideas without risk.

    Fork a project to test an idea. The main design does not change.

Customizable

Learns your team's rules and follows them on every project.

Every team builds hardware its own way. Teach Flux your standards, connect it to your tools, and let it build the small apps each project needs.

Team knowledge

Onboard Flux like a new engineer. Write your design guidelines, preferred parts, and lessons learned once, and every AI engineer in your organization applies them on every project.

Your rules

Define your layout rules and manufacturer capabilities once. Flux checks every design against them, every time.

Your tools, connected

Connect any MCP server, or give Flux a key to any web API. Push firmware to your repository, read crash reports from devices in the field, or use the tools your team built itself.

Keys stay secret

Admins add API keys once for the whole organization. The AI engineer uses them but never sees them. Flux adds each key only to requests sent to the services you allow.

Interactive pages

Ask for a one-off tool, and Flux builds it as a live page in the project: a power budget that recalculates when you change a load, a bring-up checklist that tracks progress, or a 3D assembly you can turn and take apart.

Flux in your AI tools

Use Flux from Cursor or any general AI agent that supports its tools. Your agents can read and edit Flux projects and hand design jobs to the Flux AI engineer.
