A unique integrated pipe routing design system, which allows the piping and packaging for auxiliary systems to be designed quicker and better, is the need of the hour. If this system integrates pipe-routing system design software, computer-aided drafting (CAD), and isometric visualization software to create a seamless link based on XML, it can result in a simpler pipe routing capability. This paper focuses on the packaging of the gas turbine engine, which encompasses piping accessories and the overall auxiliary system.
