Use the curve from equation functionality.

The parametric equations for a superellipse are used to define the geometry of a squircle. You can do this in Cartesian or polar coordinates.

I would evaluate the math on this as Creo represents the curves if you plan to use this as a cam profile. The curvature plot does not look right to me when using the Cartesian parametric representation of a superellipse configured to form a squircle shown in red.
