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.

Drop in STL, OBJ, PLY, or a raw point cloud from your scanner. Fluxant reconstructs, cleans, detects surfaces, fits freeform NURBS patches, and outputs native CAD rebuild scripts for 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.

Use cases

Who is this for?

Scan-to-CAD

"I have a 3D scanner"

Turn raw scans into clean CAD. Mesh repair, surface detection, STEP export, CAD macros — all in your browser. Start free, upgrade to Pro for STEP export and interactive surface placement.

See Scan-to-CAD Workflow →

Inspection

"I need to inspect manufactured parts"

Compare design to reality. Upload STEP + scan, get deviation heat maps, certified inspection reports, and audit trails. Replace Geomagic Control X at 1/50th the cost.

See Inspection Workflow →

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.
