轨道交通线路专业基于ActiveX技术进行AutoCAD二次开发的研究

Research on the secondary development of AutoCAD based on ActiveX technology in railway line of track transportation

对 Auto CAD的二次开发工具作了系统、全面的介绍与比较 ,从中选定 Active X技术 ,阐述了选择 VisualBasic作为开发语言的原因 ,给出了应用 Active X技术开发 Auto CAD的几段原代码 ,并针对北京城市铁路的部分区段 (西直门—回龙观 )进行了应用 ,证明程序的计算速度快捷、结果准确 。

The paper introduces all the tools used in the secondary development of AutoCAD and chooses the ActiveX technology after the comparison among them. The cause why Visual Basic is selected as the programming language is presented as well as the several source codesets. The method is proved to be applicable with the correct result after the quick calculation of the software when it's used to solve the partial line section (Xizhimen Huilongguan) in the Beijing Urban Railway.
