Abstract:
1. A CAD system which is realized through a processing unit of a computer, comprising: a three-dimensional layout adjustment CAD means for assisting the creation of a three-dimensional model of a pipe which constitutes a design object, and for providing pipe layout data including spool numbers; a storage means for storing previously prepared pipe specifications data; a data acquisition means for reading in the layout data and the specifications data, and for associating the layout data and the specifications data through linking keys to set the obtained data as internal data; and a spool aggregating means for aggregating the respective spools in the internal data into respective common formats to obtain format specific data, wherein the spool aggregating means comprises: a spool categorization means for categorizing the internal data into spool number units; a control point extraction means for extracting control points representing the format of each spool; a rotating means for rotating the respective spools within a prescribed three-dimensional coordinates space, on the basis of the control points so as to set the respective spools to a common layout and orientation; a table creating means for creating a table of control points in the internal data; and a comparison and classification means for comparing the tables of control points between respective spools to create format specific data which is stored separately for each spool format.
