铁路线路平纵横集成交互设计的实现

Implementation technique of integrated interactive design of plane, vertical-section and transect of railway line

运用ObjectARX的多文档界面、自定义实体以及反应器技术,建立了线路平、纵、横文档数据的自动维护机制和文档数据编辑的联动机制,实现了铁路线路平纵横集成交互设计。详细介绍了其实现技术原理和方法。该方法既保证了以AutoCAD文档为核心、数据库支撑的线路设计系统在平、纵、横多文档界面下的顺利运行和平滑切换,又实现了交互设计过程中线路平、纵、横图形的自动关联互动,使设计过程更直观方便,同时保证了线路及其相关影响因素信息的一致性。

Multiple Document Interface（MDI）, custom entity and reactors technology were used to build the automaintenance and inter-edit mechanism of document data of railway line plane, vertical-section and transect. The integrated interactive design of the three dimensions of railway line was implemented. The technical principle and technique were introduced detailed. In this way, the railway line design system based on data-base and AutoCAD document could run favourably and switch smoothly in MDI mode, and the plane, vertical-section and transect drawing of railway line can be interlinked automatically in the course of interactive design. Consequently,the design become more intuitionistic and more convenient, and the consistency of the data of railway line and its influence factors was ensured.
