Abstract
Thanks to 3D CAD modelling software the role of sections has been grown significantly. In this article we discuss the increasing role of sections. First we present some practical applications such as a section of a track and wheel and we also show how they can be used for mechanical calculations through an example of a shaft weakened with a keyway. The principle of additive manufacturing is also based on sections. Finally sections can be also used at optimizing parts, but in this paper we discuss only the case of shape optimizing
