Technical note

CDR to STL: what to expect from the conversion

CDR 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 CDR outlines into STL 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
