Is there a free version of Creo?

Could you please clarify for me, is there indeed a version of the software program Creo that is available to users without any cost? I'm particularly interested in knowing if there's a free version that offers the CORE functionalities, or if it's strictly a paid-for product with various pricing tiers. Understanding this would help me determine if it's a feasible option for my current needs and budget. Thank you for your time and assistance in clarifying this matter.
