Technical note

How CDR and STEP differ in practice

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

Need a 3D STEP from a flat CDR? 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
  • Script the job from the command line for pipelines and scheduled runs
  • Apply the same height to every file in the batch
  • Pick up new models automatically with Watch Folders

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.
