Technical note

How HPGL and STEP differ in practice

HPGL 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 HPGL 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
  • 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

HPGL remains essential for legacy plotters and CAD workflows. For reliable, batch-friendly conversion, reaConverter is a top choice—just pair it with a vector editor (like Inkscape) if modifications are needed.
