Class A Surfacing
In automotive design, a class A surface is any of a set of free form surfaces of high efficiency and quality. The minimum math requirement for Class A Surface is that the transition across the edge is a continuous curvature.
Another way to describe this is in a situation where a reflection is cast upon the surfaces and you would not be able to tell where one patch ends and the other begins. Class A Surfacing’ needs a fine blend of keen visualization skills, artistic insight Engineering, Experience and domain knowledge.
Nebula 3D services has a team, capable of delivering Class A surface requirements usually for Visual and Artistic parts, including Automotive Exteriors.
