A Modeling Language for 3D Process Plant Layout Representation, Exchange and Visualization

Abstract

Abstract. In the nuclear industry, achieving Long Term Data Preservation is a requirement for nuclear power plants to be safely built, operated over five or six decades and retired. Among them, CAD data suffers from some strong dependencies on the software vendors and its data model thus leading to a possible weakness in the preservation workflow. This paper presents a modeling language, suitable for the 3D representation of a process plant layout, based upon a procedural Constructive Solide Geometry (CSG) approach. The language execution, as well as the layout rendering and exchange, are experimented using a platform independent implementation, based on free software and open standards.
