Abstract: A data processing system for automated design of a piping system and method thereof are disclosed. In one embodiment, a method for automated design of a piping system includes obtaining logical definition data of the piping system with pipe runs from a computer-aided design (CAD) database, and computing a piping path for said each pipe run based on the logical definition data of the piping system. The method includes determining positions of the piping components required for said each pipe run according to the logical definition data based on the computed piping path, and associating the piping components for said each pipe run with the determined positions of the piping components. Moreover, the method includes automatically generating a graphical model of the piping system with the pipe runs based on the association of the piping components with the determined positions for said each pipe run.
