How It Works

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

Technical note

AI to OBJ: what carries over and what does not

AI is flat, so the conversion builds depth by extrusion: every closed outline is lifted to one height, set in millimetres in the 3D formats loading settings. An open line has no area to lift, so a drawing meant for extrusion needs closed contours. Every shape gets the same height, which suits plates, signs and logos, while parts at different heights need separate runs.

3D Workflow

From flat drawing to 3D model

reaConverter turns AI outlines into OBJ models by extrusion, so a flat shape becomes a 3D part in one step.

  • Set the extrusion height in millimetres before the run
  • Convert a whole folder of drawings in one pass
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs

Client demanded PNGs but sent AI files ‘because you have Adobe, right?’ Jokes on them—reaConverter handled it while I sipped my coffee.

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.
