3D Workflow

Move models between 3D formats

Every 3D tool has its own format, and IGS is not always the one you need. reaConverter converts it to IGES in batch, without Blender or a CAD licence.

  • Convert a whole model library to IGES in one run
  • Pick up new models automatically with Watch Folders
  • Set the level of detail from 1 to 7: finer triangles for smooth curves, fewer for small files
  • Keep unreleased designs and client models on your PC: nothing is uploaded
