Piping Design for Production Facilities Using 3D CAD

Shinji Yoshida, iCAD Ltd., Japan

Abstract. Many designers design production facilities using three-dimensional computer-aided design (3D-CAD) software. Production facilities typically have many machines and piping structures. Designers design the piping routes while designing the machines of a production facility. Designers may change the shapes of some machines when designing the piping routes because they must arrange the piping within the limited space availability. The design of piping is best done using a 3D model of the machines in the facility because the machines and piping affect each other. However, in piping design, designers typically use simplified shapes as substitutions for the detailed shapes of machine models. The reason for this is that traditional 3D-CAD cannot handle the types of massive 3D models that are often required for production facility design. In other words, designers usually must design piping routes using simplified shapes as substitutes for the detailed shapes of machine models. As a result, some fatal problems, such as interference between piping and machines, can occur in real assembling work. In previous research, we proposed a data structure that can handle the data of massive 3D models such as production facilities. In this paper, we propose a method to address this issue by applying this data structure to piping design.
