How It Works

reaConverter offers the fastest, simplest solution for converting your PNM files into U3D in seconds - all images processed on your PC for maximum privacy and speed.

3D Workflow

From picture to 3D model

reaConverter traces PNM images into outlines and extrudes them into U3D models, so a logo or a sketch becomes a 3D part in one run.

  • Each image is vectorized first, then extruded to the height you set in millimetres
  • Works best with logos, signs and line art: a photo has no clean outlines to follow
  • Pick up new models automatically with Watch Folders
  • Apply the same height and tracing settings to every image in the batch
