Some NX features claim to create "Class A quality" surface. In the official documentation very little information can be found on "Class A quality" surface. Some information from other software documentation can be found on web.
Q1: What does it mean exactly (not roughly "better quality") when a feature claims to create "Class A quality" surface"?
Q2: Where can I find more information on "Class A quality" surface, especially guidelines for constructing it with common NX features?
Thanks!
