Class A surface refers to those surfaces which are VISIBLE and abide to the physical meaning, in a product. This classification is primarily used in the automotive and increasingly in consumer goods (toothbrushes, PalmPC's, mobile phones, washing machines, toilet lids etc.). It is a
requirement where aesthetics has a significant contribution. For this reason the exterior of automobiles are deemed Class-A. BIW is NOT Class-A

Hi Prakash,

Class A is
1.Visible surface and aesthetic look
2.surface with textures
3.Surfaces provided by customer(OEM)
4.Don't have any features like(rib,snap,bosses etc) on class A surface.
5.Class A surface is made from scanned data with different software like allias etc..
6.Surfaces which is having CURVATURE CONTINUITY IS CALLED class-A.

Class B surface:
1.invisible Surfaces.
2.Surface mostly don't have textures
3.Surface need to be create according to class-A surface.
4.having all features(Rib,boss,snap etc) in B-side surface only.
5.Surfaces which is having TANGENT CONTINUITY IS CALLED class-B

I Hope u can get little idea from the above point.
Thanks for you question

Styling or A class surface are the terms used in plastic product design. That mean the surface of a component which is smooth( aesthetic) or visible side to human eye after the part is assembled.
we can also consider the outer surface of exterior (in automotive) as styling though it not plastic.
but Bumpers, side mirror housing, lightening systems and fender in many cases are plastic (exterior trims).
The entire visible plastic surfaces you see inside the car( Dash board or ip, door panels, etc.) are A surfaces. even the visible surface of bumper, fender, mirror housing, etc
smooth finish of a surface is high priority.
Hopes helpful:)
