Abstract: The AUTOCAD,a favourable and powerful drawingsystem of person-computer talk,is widelyused in many fields.The interface technique between advanced computer langua8e and AUTOCAD,however.has barely been reported.This paper develope the interface technique between FORTRAN andAUTOCAD Compretiensively and systematically,The various drawing routines written in FORTRANare described.and an example is showed to call the drawing routineei,This interface technique has beensuccessfully used in a network analysis program of cable-stayed bridge construction.

Key words: FORTRAN, AUTOCAD, Interface-technique

摘要： AUTOCAD的交互图形功能极强，应用较广泛，受到软件工作者的青睐。而有关高级语言同AUTOCAD数据接口技术的报导较少，成功地采用其接口技术的应用软件还不多见。本文较全面、系统地阐述了FORTRAN语言同AUTOCAD的数据接口技术，列出基本图形接口子程序，并给出调用示例。该技术已被成功地应用于斜拉桥施工网络分析程序中。
