3D Workflow

From picture to 3D model

reaConverter traces JPC images into outlines and extrudes them into STP 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
  • Apply the same height and tracing settings to every image in the batch
  • Keep unreleased designs and client models on your PC: nothing is uploaded
