3D Workflow

From picture to 3D model

reaConverter traces MAC images into outlines and extrudes them into STEP 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
  • Tune the tracing precision so the edges follow the original
  • Pick up new models automatically with Watch Folders

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!
