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.

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.
