3D Workflow

From picture to 3D model

reaConverter traces JPP 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
  • Script the job from the command line for pipelines and scheduled runs

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.
