Design of Visiting MDT Solid Model Program Based on ObjectARX

Based on a close research of the interior representation of CAD model in MDT, ObjectARX application program is developed using the development tools of ObjectARX and MDT API offered by Autodesk Inc in MDT environment, according to which the database is expatiated particularly. So that this thesis picks-up the interior topological and geometrical information of model expressed in the boundary representation (B-Rep). The picking-up information makes it successful to visit the database in MDT.
