CAD DATA CONVERTING METHOD, CAD DATA CONVERTING SYSTEM, CAD DATA CONVERTING PROGRAM AND METHOD FOR MANUFACTURING ELECTRONIC CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide interchangeability of data between CAD systems for an electronic circuit board of different models.;SOLUTION: A first CAD system 100 and a second CAD system 200 are configured as a CAD system for an electronic circuit board. First drawing data are read from a first drawing data file 63a created by the first CAD system 100, and elements whose electric connection relationship is specified by wiring net data(net) configuring one portion of attribute data are grouped by every layer and every element classification so that a list representing the attribute data of elements configuring the first drawing data can be generated. The attribute data of elements mentioned in the list are converted into attribute data for plotting processing in the second CAD system 200. The elements mentioned in the list are written in a plotting layer based on the converted attribute data so that a second drawing data file 63b can be obtained.;COPYRIGHT: (C)2005,JPO&NCIPI
