How It Works

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

Technical note

Before you convert OBJ to IGES

OBJ stores a surface made of triangles, while IGES is built for exact solid geometry. The conversion has to derive surfaces from that triangle mesh, so the result is faithful to the shape but is not the same thing as a parametric model with clean features and editable dimensions. OBJ holds bare numbers with no unit, and IGES has to state one, so the conversion has to assume it. If the OBJ was exported in inches or metres, the result is off by that same factor. Measure one known dimension after conversion.

3D Workflow

From mesh to CAD format

reaConverter converts OBJ models to IGES for CAD, quoting and archiving, a whole folder at a time.

  • Get each model as one IGES file that SolidWorks, Fusion or FreeCAD can open
  • Convert a whole model library in one run with the same settings
  • Pick up new models automatically with Watch Folders
  • Render preview images of the same models in a second run

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.
