Technical note

HPGL to U3D: what to expect from the conversion

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

Need a 3D U3D from a flat HPGL? 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
  • Apply the same height to every file in the batch
  • Pick up new models automatically with Watch Folders
  • Convert a whole folder of drawings in one pass

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.
