Abstract

A logical designing part includes a logical connectivity data storage that stores logical connectivity data, indicating a logical connectivity between plant equipments, including first end point connection data. A geometry data designing part includes a geometry data storage that stores geometry data that is graphical shape data in a three-dimensional space and includes second end point data. A data linking part includes: an automatic correspondence table generating part that compares first end point connection data with second end point data and generates a logical connection and geometry data table including correspondence data that links the geometry connection data and the geometry data of which first and second end point connection data are matched each other. A correspondence storage stores the logical connection and geometry data table. An editing part edits the logical connection and geometry data table on the basis of a user command.
