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.](https://flux.seobdtools.com/p/assets/homepage-v2/teams-step-edit-psu-before.webp) 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.](https://flux.seobdtools.com/p/assets/homepage-v2/teams-step-edit-psu-after.webp) 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.

Yes. Ask Flux to design an enclosure around the board. Flux uses the board outline, mounting holes, connector positions, and part heights. It aligns the supports to the mounting holes, adds openings for the connectors, and leaves space for cables and displays. See [ECAD and MCAD Co-Design](https://docs.flux.ai/reference/ecad-mcad-co-design). ### My board is in another ECAD tool. Can Flux still design the enclosure? Yes. Upload the IDF 2.0 or 3.0 board file (.emn) with its part library (.emp). Flux imports the board outline, cutouts, holes, part placements, and part heights, then designs the enclosure around them. You can also import the board from Altium, KiCad, and other ECAD tools and continue the electronics in Flux. ### Which enclosure features can Flux design? Two-part shells, removable lids, snap fits, screw bosses, ribs, draft angles, parting lines, hinges, vents, battery compartments, and connector openings. Flux also designs sheet-metal covers and chassis with bends, flanges, and a DXF flat pattern. ### How does Flux check that the board fits? Flux checks interference between the board and the enclosure, the space in front of each connector, and tool access to each screw. It computes worst-case and RSS tolerance stack-ups from the board to the enclosure and proposes changes. In the 3D view, you can cut through the assembly and measure any gap. See [Fit and Clearance](https://docs.flux.ai/reference/fit-and-clearance). ### What happens when the board changes? Tell Flux what changed. Flux updates the openings, supports, and lid clearance to match the new connector positions, mounting holes, or part heights. When the enclosure changes, Flux can update the board outline and move parts to keep clearance from the walls. ### Can Flux simulate airflow and heat in the enclosure? Yes. Flux simulates air flow and temperature inside the enclosure with vents, fans, and heatsinks, and heat conduction through the enclosure wall. It reports peak temperatures, outlet air temperature, and flow rates. See [Simulation](https://docs.flux.ai/reference/simulation). ### Can Flux design an enclosure from a sketch or a photo? Yes. Attach a hand sketch, a photo, a render, or a dimensioned drawing in the chat. Flux matches its proportions and dimensions and builds the enclosure for the board in your project. ### How do I manufacture the enclosure? Flux checks the part against the limits of SLA, SLS/MJF, CNC milling, sheet metal, laser cutting, and injection molding. Export STEP, STL, or 3MF, create a dimensioned drawing with GD&T, and ask Flux for 3D-print, CNC, and sheet-metal quotes. ### Can Flux add screws, inserts, and standoffs? Yes. The part library has screws, nuts, washers, threaded inserts, standoffs, fans, and heat sinks with 3D models. Ask Flux to find the hardware and place it at the enclosure mounts. ### Can Flux design more than enclosures? Yes. Flux designs brackets, mounts, mechanisms, and complete products, and the electronics and firmware inside them. See [Flux for mechanical design](https://flux.seobdtools.com/p/mcad) and [Flux for electronics design](https://flux.seobdtools.com/p/eda). ### How much does it cost? The [Teams plan](https://flux.seobdtools.com/p/pricing) is $500 a month with shared seats and AI usage units, and covers mechanical, electronics, and firmware work. ![Hands holding an assembled board in its enclosure.](https://flux.seobdtools.com/p/assets/homepage-v2/photos/L1008492-1920.webp) ## Design the enclosure with the board.
