This study focuses on the comparative analysis of Creo and Rhnio software

among which Creo performs outstandingly in the field of parametric design. Its integrated free-form surface design FDX module can seamlessly integrate free-form surface processing and solid modeling functions. In contrast

Rhnio combines its precise 3D modeling capabilities with Keyshot's real-time realistic rendering technology to create an efficient 3D design solution in the current product design field. This study conducted an in-depth comparative analysis of these two software from three dimensions: the flexibility of appearance modeling

the convenience of model modification

and the smoothness of the design process

and further analyzed their respective advantages and focuses in product design practice. Intended to provide practical guidance for college students when choosing design tools

as well as useful references and inspirations for research and practice in the field of product structure design and modeling analysis.
