箱梁构造图三维快速建模的目标包括模型的高精度和构建的高效率,为解决这两个问题,提出了一种基于Vlisp和OpenDCL的参数建模方法 ,利用图层自动读取和对象截取的方法来获取结构平面线形和高程,使用参数自动读取的方法节约输入参数的时间。先绘制二维构造图,以图中信息为基础进行面域拉伸或放样,构建三维模型,实现了箱梁三维构造图精确、快速建模,解决了设计人员传统三维建模易错、耗时的难题,提升了建模效率,为基础设施领域的三维快速建模提供一个新的思路和方法。
The goal of three-dimensional rapid modeling of box girder structure includes the high precision of the model and the high efficiency of the construction. To solve these two problems, a parameter modeling method based on Vlisp and OpenDCL is proposed, which uses layer automatic reading and object Intercept method to obtain the structure of the plane line and elevation, the use of automatic reading parameters to save input parameters of the time. First draw the two-dimensional structure, the information in the drawing as the basis for the area stretch or lofting, build three-dimensional model, the box girder to achieve three-dimensional structure accurate and rapid modeling, to solve the traditional three-dimensional modeling error, consumption When the problem is difficult to improve the modeling efficiency and provide a new idea and method for 3D rapid modeling in the field of infrastructure.
