| For the purpose of its intended use, CAD files maintain information/data about solid models. Efforts have been made in this study to create an access to the CAD data for the purpose of extending the application of CAD modeling.; Although CAD software does not allow access to its native data, there exist some translator utilities to support migration of CAD models from one CAD system to another. IGES (initial graphics exchange specification) is one such translator utility that can translate a CAD file into an ASCII format file. The industry supporting this study is also using ICES. In this study, ASCII format IGES files have been used to access the geometry data of CAD models. For this purpose, AutoCAD 14 and Mechanical Desktop 3 have been used as CAD software, and IGES 5.3 has been used as the ASCII format translator.; A software tool has been developed in Java to automate the process of extraction of geometry data of CAD models.; Using the extracted geometry data of a CAD model, a visual modeling application has been developed in this study.; To support the modeling operations as well as to enable extensions to some other applications, a database has also been developed using DB2 software of IBM.
