Step by step

How It Works

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

3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not IRRMESH files. reaConverter renders each model to FITS at the angle you set, a whole folder at a time.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Use one angle and size for every model, so a catalogue looks consistent
  • Script the job from the command line for pipelines and scheduled runs
