摘要： 针对传统的预应力混凝土连续梁桥主体结构BIM 建模方法效率低下、数据稳定性
无法保证的问题，使用达索/CAA 二次开发语言，遵循“骨架-模板”建模思想，开发出一种预应
力混凝土连续梁桥主体结构建模工具。以用户输入窗口和Excel 表格作为数据传递媒介，充分
利用CAA 的几何建模工具、特征建模工具、物理建模工具，通过界面模块、特征模块、节段
拓扑模块对程序内部结构的合理组织，最终实现节段自定义特征的实例化和连续梁节段零件组
装。结果表明，该建模工具能够大幅度提高建模效率并保证数据稳定性，且为基于达索/CAA
二次开发的其他BIM 研究提供了基本思路和方法。

Abstract: Traditional building information modeling (BIM) modeling method forcontrete continuous
girder main structure is inefficient, and the data stability is not guaranteed. To prevent the defects of
traditional modeling method, this paper develops a modeling tool for concrete continuous girder,
following the “skeleton-template” modeling idelogy. Taking user dialog window and excel table as
the delivery medium, by dint of geometry modeler, feature modeler, mechanical modeler, the
program’s interstructureis reasonably arranged through interface module, feature module and segment
topological module. Finally, segment feature instantiation and segment parts assembly is successfully
realized. It indicates that this modeling tool can highly improve the modeling efficiency and
guarantee the data stability. This paper also supply other BIM resrarches which is based on
Dassault/CAA secondary development with insparition and method.
