Abstract
In order to implement the integration of the tool libraries from CATIA and the tool database, CATIA software was further developed using CAA. CAA macro-based integration project about the two libraries is proposed, and the development process is presented. In CAA environment provided by CATIA, though further developed using CAA, calling for information, converting information and valuating information of CATIA and TOOLMANAGER were researched. Finally, the dynamic calling, association and driving of CATIA-based tool information were implemented successfully.
