Abstract:

In order to construct a typical CA TIA tool component library , to implement the query , preview and use of the components , and to display the main parameters in a 3 D space , the construction and queηprocesses of the standard part librarγare investigated , and a general frame of the construction tool for the component library is put forward. Some key techniques for the library construction and the corresponding implementation methods are then
discussed , such as the modeling method of the component entity , the design of the parameter table and the CAA API-based preview and instance of the compo口ents. Moreover , a construction tool of component library is designed and developed based on CATIA. The tool is finally applied to an enterprise. The results show that the tool is of great applicability and helps to improve the design efficiency and production interchangeability.
