AutoCAD环境下的铁路线路平纵横集成交互设计

Integrated Interactive Design of Plan with Profile and Cross-section of Railway Line in AutoCAD Environment

运用ObjectARX的多文档界面、自定义实体以及反应器技术,建立了线路平面、纵断面、横断面文档数据的自动维护机制和文档数据编辑的联动机制,实现了交互式铁路选线设计过程中线路平、纵、横的一体化设计和图文数据的实时互动。该方法使设计过程更加直观方便,同时又保证了线路及其相关影响因素信息的一致性。

Multiple Document Interface, custom entity and reactors approach in ObjectARX are used to accomplish the auto-maintenance and interactive-edit of railway line document data in the three consecutive stages of plan design, profile design and cross-section design. Integrated design of plan with profile and cross-section and real time association of the graphics-attribute data are implemented in the process of railway line location in interactive mode. The design process becomes more intuitive and straight forward, and the consistency of railway line data and its related influence factors is ensured.
