Increasing Role of Sections Caused by 3D Modelling

Abstract

In the last years the role of sections has been grown significantly thanks to solid modelling. Earlier objects were defined by 2D drawings, while cuts or sections were only used for representing their inner parts in case of need. After a short review of types and rules of section drawings we discuss the different ways how objects can be defined with their sections using 3D modelling software.  Finally we discuss that creating solid objects can be used not only in technical but as well as in medical practise. To illustrate them we show examples for both cases: a pump and a human skull.
