Technical note

HPG to STEP: what carries over and what does not

HPG 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 STEP from a flat HPG? 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
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs
  • Apply the same height to every file in the batch

reaConverter handles HPG files flawlessly. I use it to convert plot files to PDF for approvals, and the output is always accurate. The automation through Watch Folders and command-line is a big plus for speeding up our workflow.
