Abstract：Even in AutoCAD,writing of Drawing List for Assembly is humdrum and apt to make careless mistakes.The paper discusses the method to implement auto-writing of Drawing List by combining the xdatas of ARX′s database object,which record parts information while the part numbers are drawed,with ODBC database technique.The method has been employed in programming of software HYCAD and is proved can work as expectedly.The experience has proved that combing xdatas of ARX′s database object with ODBC database technique can fulfill the unified information management and interaction of drawing objects.
