プラント配管CADにおける空間の取扱い : 基本モデルとその応用

概要

論文の詳細を見る
In this paper, we present a complete soft model for a plant piping CAD, which takes into consideration not only the piping elements but also the spaces among piping lines. Using this model, we can recognize the volume of the space among pipe lines digitally, instead of the intuitive view of the figure on the screen. A plant space is divided into many sub-spaces called "ragion space" by piping line segments. This region space is defined by the shape of the rectangular solid and can be handled on the same level as the piping element data in piping CAD system. As the specific design works used this space model in CAD system, we can achieve computerized checking of the total interference of piping lines as well as maintenance space checking of valve parts. We also report the concept of region space, the procedure for data base construction and the application program in the piping CAD system.
