Today’s products are not only designed considering their functionality, but special consideration is given to their form and aesthetics which is crucial in the perception and reality of a quality product to the consumer.
‘A’ Class Surfacing
‘A’ Class surface definition. Class ‘A’ surface refers to those surfaces which are visible in a product. This service is primarily used in the automotive environment and increasingly in consumer goods. It is a requirement where aesthetics have a significant contribution. E.g. the exterior of automobiles are deemed Class-‘A’.
Why would you require Class ‘A’ surfacing. We all know that today’s products are not only designed considering the functionality but special consideration is given to their form and aesthetics which is crucial in the perception and reality of a quality product to the consumer. This quality is only possible with high-class finish and good forms. This is the reason why in design industries, Class ‘A’ surface are given more importance.

‘A’ class surfaces are those aesthetic free form surfaces, which are visible surfaces either interior or exterior, having an optimal aesthetic shape and high surface quality. The ‘A’ class surfaces have continuous curvatures with no undesirable waviness.
These surfaces are predominantly used in the automotive industry where aesthetic finish is crucial, however class ‘A’ surfacing is applied to many other sectors.
Curvature continuity: It is the continuity between the surfaces sharing the same boundary. Curvature continuity means that at each point of each surface along the common boundary has the same radius of curvature and therefore the boundaries have been blended so no physical joint is present or visible.
Literal meaning: A class ‘A’ surface refers to those surfaces, which are ‘curvature’ continuous to each other at their respective boundaries. Curvature continuity means that at each “point” of each surface along the common boundary has the same radius of curvature.
This is different to surfaces having;
1. Tangent continuity – which is directional continuity without radius continuity – like fillets.
2. Point continuity – only touching without directional (tangent) or curvature equivalence.
