The short version

  • Only OpenSCAD has a free tier, so it costs nothing to try first.
  • Each has a real cost: CATIA pricing page discloses no figures and instead asks buyers to "Speak with a CATIA expert" or "Contact us" through a how-to-buy form, making pricing available only by quote; OpenSCAD script-based workflow, not interactive design interface
  • They diverge on capability: CATIA covers Surface modeling, OpenSCAD covers Script-based modeling.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CATIA

  • Pricing page discloses no figures and instead asks buyers to "Speak with a CATIA expert" or "Contact us" through a how-to-buy form, making pricing available only by quote

OpenSCAD

  • Script-based workflow, not interactive design interface
  • Limited to constructive solid geometry and 2D extrusion modelling
  • Not suitable for artistic 3D modelling or computer animation
  • Complex build dependencies (Qt, CGAL, Boost)
