Hello, I wonder what's the difference between a technical surface and an aestethic surface, the only thing I found was: "The technology has encompassed two main fields. Either creating aesthetic (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering components."  Can someone explain in a short version?

Did you find an answer yet?

No I have not found anything!

"Aesthetic shapes are usually actualized as 3D objects represented by
free-form surfaces. The main components used to achieve aesthetic
surfaces are 2D and 3D curves, which are the elements most basic for
determining the shapes and silhouettes of industrial products. Bézier,
B-Spline and NURBS are types of flexible curves developed for various
design intents."Quoted from the abstract "Aesthetic Curves and Surfaces in Computer Aided Geometric Design" by Mirua and Gobithaasan, January, 2014.

Isn't a Class A Surface also known as an aesthetic surface?https://en.wikipedia.org/wiki/Class_A_surfaces
