基于AutoCAD二次开发技术的城市轨道交通刚性接触网辅助绘图软件设计

在城市轨道交通刚性接触网设计中，为实现快速标准化的绘图，基于AutoCAD二次开发技术设计一款城市轨道交通刚性接触网辅助绘图软件。软件以Visual Studio 2008为开发平台，采用ObjectARX开发环境进行编程。归纳了刚性接触网锚段形式并建立标准锚段数据库，辅助绘图软件通过Excel COM组件调用数据库内预存的悬挂点坐标，实现刚性接触网参数化和标准化地绘制。研究成果及所开发的软件已应用于实际工程中，提高了绘图效率和准确性。

Urban rail transit rigid catenary aided drawing software based on AutoCAD secondary development

In order to achieve rapidity and standardization drawing in rigid catenary design for the urban rail transit,an aided drawing software was designed based on the AutoCAD secondary development technology. The software was developed on Visual Studio 2008 and programmed with the ObjectARX. The form of the anchoring section was summarized, and the standard anchor sections database was established. The auxiliary drawing software calls the prestored hanging point coordinates in the database through the Excel COM component to implement the parameterization and standardized drawing of the rigid catenary. The research results and the software developed have been applied to practical engineering, which improves the efficiency and accuracy of drawing.
