Abstract: As the sectors of ship design and manufacture, the design institutes and shipyards usually receive a large number of technical design results from supporting sectors or upstream sectors. In order to upload these extern al technical documents quickly, a method of batch importing was developed based on Windchill. By this method, a new action was added to drop-down list in Windchill user interface. Then, a JSP page was linked to the action t o upload external technical documents by using Excel table forms. Finally, the Java code is added to the Windchill system to handle with the process of uploading. This method can be applied in Windchill PDM management for design institute and shipyards.
