reaConverter offers the fastest, simplest solution for converting your AMJ files into CG4 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 AMJ files. reaConverter renders each model to CG4 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
  • Draw isometric, top, front or side views as line drawings with 2D projection
  • Pick up new models automatically with Watch Folders
  • Render a turning model as an animated GIF when one still image is not enough
