【摘要】 当前AutoCAD的图形输出存在着很多对外不公开文件格式,为实现加工信息的集成及数控加工,必须对AutoCAD的图形文件进行访问、读取、转化成我们所需要的格式,所以对访问AutoCAD图形文件的方法必须进行深入分析,详细地论述访问AutoCAD的图形文件的LISP、VBA、DXF、Ob jectX ARX等各种方法的优缺点,从而可根据不同的开发环境,选择合适的开发方法,以提高工作效率。更多还原

【Abstract】 Nowadays,there are some file formats which are not in open in outputs of AutoCAD graphic files.For realizing integration of machining information and machining of NC(numerical control),We not only visit and read AutoCAD graphic files,but also transform theirs file formats to which we can availably utilize.Therefore,the Paper which deeply analyzes the five methods on visiting AutoCAD graphic files,such as LISP、VBA、DXF 、ObjectX ARX,and so on.And concludes the merits and defects of each method.For improving the Work efficiency,we can choose the feasible development methods based on different environment.更多还原
