Class A

This article explains the concept of construction engineering. For the operating mode in the amplifier technology, see output stage . To see foam Polyvalent foam agents . For the network area see network class .

Comparison Class A vs. Class B

The term Class A describes visible (freeform) surfaces in the exterior and interior area of product development . It is mainly used in automotive development. Surfaces designated with Class A usually have curvature continuity.

The categorization of surfaces in Class A , "Class B" and "Class C" is carried out in order to be able to classify the surfaces in terms of their intended use.

"Class B" surfaces are the inner surfaces of Class A surfaces that are normally not visible to the user and the load-bearing structure of the object. Finally, "Class C" surfaces are those surfaces that are only used temporarily for tool manufacture, or the surfaces of the tools that are used to generate Class A and "Class B" surfaces (e.g. the shaping surfaces of Deep drawing tools).
