Technical note

PDF to STEP: what to expect from the conversion

PDF 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 PDF outlines into STEP models by extrusion, so a flat shape becomes a 3D part in one step.

  • Set the extrusion height in millimetres before the run
  • Script the job from the command line for pipelines and scheduled runs
  • Apply the same height to every file in the batch

This article was a lifesaver! I quickly converted multiple JPG files to PDF with ease. Other sites I visited only offered downloadable programs, but your online converter delivered instant results! Way more efficient!

PDF is certainly a universal format, but sometimes you need JPEG files instead. For conversion, I use reaConverter - a lightning-fast program. No online editor can match its speed. Install it once, and you're set. Just open, convert, and done!

We use reaConverter to merge multiple PDFs into one and compress them for email attachments. The batch mode is a godsend – we process 50+ documents every week. Never had a single error or corrupted file. Highly recommended!
