The short version

  • Only OpenSCAD has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arnold the Internet Archive's capture of Autodesk's Arnold overview page on 30 December 2022 stated a subscription can be installed on up to 3 computers or devices, though only the named user may run it on one machine at a time, and includes access to the 3 previous major versions.; OpenSCAD script-based workflow, not interactive design interface
  • They diverge on capability: Arnold covers Ray tracing, OpenSCAD covers Script-based modeling.
