The short version

  • Each has a real cost: Inventor autodesk publishes no licence price through UK G-Cloud: every listing found there is reseller delivered training at 750 to 1,500 pounds per day rather than software licensing, and neither AWS Marketplace nor GSA carries the product; RFPIO pricing not publicly disclosed; three tiers (Emerging, Growth, Enterprise) but no published costs
  • They diverge on capability: Inventor covers Parametric modeling, RFPIO covers Answer library.
