How It Works

reaConverter offers the fastest, simplest solution for converting your CSM 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 CSM 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
  • Pick up new models automatically with Watch Folders
  • Render a turning model as an animated GIF when one still image is not enough
