Technical note

Before you convert PDF to U3D

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

Need a 3D U3D from a flat PDF? reaConverter extrudes the outlines to the height you set and processes a whole folder in one run.

  • 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

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!
