Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your MS3D files into IGS without 3D or CAD software - all models processed on your PC for maximum privacy and speed.

3D Workflow

From mesh to CAD format

A CAD system or a supplier asks for IGS, and the model exists only as MS3D. reaConverter writes it to IGS in batch, offline.

  • Get each model as one IGS file that SolidWorks, Fusion or FreeCAD can open
  • Render preview images of the same models in a second run
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
