Step by step

How It Works

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

3D Workflow

From picture to 3D model

reaConverter traces CPT 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
  • Pick up new models automatically with Watch Folders
  • Apply the same height and tracing settings to every image in the batch

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
