What is Class A surface in CATIA?

Mathematically class A surface are those surfaces which are curvature continuous while providing the simplest mathematical representation needed for the desired shape/form and does not have any undesirable waviness. Curvature continuity: It is the continuity between the surfaces sharing the same boundary.
