摘　　要：在研究多种钢桁梁桥的结构特点、杆件类型的基础上,运用VC++和ObjectARX开发技术,建立图层、颜色、线型、文字和标注样式等绘图环境设置接口函数,开发图形绘制、尺寸标注、文字书写等接口功能,根据钢桁梁杆件参数的不同,创建各种杆件的参数化绘图和符号标注子模块,实现钢桁梁杆件的参数化绘图,为钢桁梁桥的参数化绘图提供了新的思路和方法。On the basis of the structural characteristics of various kinds of steel truss bridge and member models, interface functions of drawing environment settings for setting layer, color, line type, text and marking style are established, and the interface services to draw graphics, mark dimensions and write characters are developed. According to the different parameters of steel truss members, parametric drawing and symbol annotation sub-module for various members are created, parametric drawing for members of steel truss bridge is fulfilled, and then new concept and method for parametric drawing of steel truss bridge are proposed.
