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.

Thanks for your support.

I have made the shape using the equation available on the web.

Use the curve from equation function. The Cartesian equation of a superellipse is used to create the squircle.
