3D Workflow

From picture to 3D model

Need a 3D STEP from a flat QRT image? reaConverter vectorizes it, extrudes the shapes to the height you set, and works through a whole folder at once.

  • 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
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs

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!
