3D Workflow

From flat drawing to 3D model

reaConverter turns PRN 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
