Look through this thread to have some modeling options.

Re: Another workaround for 3-side surface - PTC Community

If you are designing a prop blade for aerodynamic performance, then building it using freehand curve and surface patches is not how it is typically done when the propulsion engineers are designing the geometry. Analytic models often start with curve driven equations and or points/curves that are then imported into Creo and used as the basis for surface modeling of the aero surfaces.
