Development Of The Aided Design Software For Electronic Products Based On AutoCAD2004

Due to the structural limitations of electronic products, some enterprises and sectors of the electronics industry produce the electronic products by the way of artificial connection, instead of by printing circuit board. These enterprises and sectors can use the remote identification method to designing electronic products in order to correctly expressing the designer’s design intent and to facilitate the reading work. But when using the remote identification method, the designers need to complete the work, such as checking remote error and designing wiring statements, which is time-consuming and error prone.Based on AutoCAD2004and ObjectARX, the aided design software for electronic products is developed for reducing designers’work and improving production efficiency. Several contents of the study are mentioned as follows:Firstly, the structure of AutoCAD files is introduced. The major elements of the drawing, such as schematics designed by the remote identification method, title bars and parts lists, are analyzedSecondly, according to the characteristic of schematics, the wiring data in schematics is extracted, and an error-checking algorithm is put forward. With the wiring data and the error-checking algorithm, remote error is checked out and the wiring data is processed. According to the processed wiring data, wiring statements are designed.Finally, a title data extracting algorithm which based on attribute extraction method, and a parts list data extracting algorithm which based on key point discriminating method are put forward. According to the algorithms, the detail data of title bars and parts lists is extracted. According to the detail data, detail statements are designed.
