100% client-side WebAssembly engine

DECODE
REALITY

Drop a STEP file, a 3D scan, or any mesh. Fluxant extracts exact geometry, detects features, generates native CAD macros, and runs deviation inspection — all in your browser. Files never leave your device.

What Fluxant does

One engine. Three high-value jobs.

Most tools do one of these badly. Fluxant does all three in one browser tab.

Open CAD

Open STEP, STP, and IGES without desktop software. Inspect assemblies, measure exact geometry, and export what you need.

  • Exact B-Rep parsing via OpenCascade.js
  • Assembly tree with show/hide/isolate
  • Mass properties + material weight estimation
  • Cross-sections at any plane → SVG export
  • 100% confidence on all extracted features

Rebuild Scans

Turn raw 3D scans into clean geometry, detected surfaces, and native CAD rebuild scripts.

  • Auto-repair: holes, normals, manifold topology
  • VSA surface detection — color-coded regions
  • Feature recognition: holes, fillets, chamfers, pockets
  • SolidWorks VBA / Fusion Python / FreeCAD Python
  • Quality tiers: Production / Balanced / Preview

Inspect Reality

Compare design intent to manufactured reality. Get deviation heat maps and pass/fail inspection reports.

  • Upload STEP (design) + scan (as-built)
  • Color-coded deviation: green/yellow/red
  • Min/max/mean/RMS statistics
  • Pass/fail inspection report generation
  • Replaces $10-15K inspection software

Open exact CAD in a browser. Not a viewer pretending to be one.

Someone emails you a STEP file. Fluxant gives you something useful immediately: exact measurements, assembly structure, mass properties, cross-sections, and clean mesh exports. No desktop CAD license required.

Scans stop being triangle soup.

Upload any STL, OBJ, or PLY mesh. Fluxant repairs geometry, detects surfaces, identifies features, and outputs native CAD rebuild scripts that construct a parametric feature tree in SolidWorks, Fusion, or FreeCAD.

See what was designed to what was actually made.

Upload the nominal STEP design and the scanned manufactured part. Fluxant aligns both, computes point-to-surface deviation, and generates a pass/fail inspection report — in one browser tab, without $15K software.

Proof

No logos yet. Just a working engine.

Exact CAD parsing

STEP and IGES files parsed via OpenCascade.js WASM with full B-Rep topology preserved.

Mesh reconstruction

Repairs, decimation, surface detection, feature recognition, and rebuild scripts from scan data.

Inspection workflow

Deviation heat maps, tolerance analysis, and pass/fail reporting from design vs manufactured parts.

Privacy by architecture

All processing runs client-side via WebAssembly. Files never touch a server. Not by policy — by design.

Built by one person. Running today. Launching soon.

Real geometry software. Not a cloud wrapper.

Fluxant runs exact CAD parsing, mesh reconstruction, feature detection, and deviation analysis entirely in your browser via WebAssembly. Large files stream in chunks, process in tiles, and stay on your device. Privacy is architectural, not a checkbox.
