The short version

  • Only OpenSCAD has a free tier, so it costs nothing to try first.
  • Each has a real cost: Inventor pricing shown as template variables on the page, suggesting dynamic or region-specific pricing; OpenSCAD script-based workflow, not interactive design interface
  • They diverge on capability: Inventor covers Parametric modeling, OpenSCAD covers Script-based modeling.
  • Prices and features above were last checked on 30 August 2026.
