摘要:建筑模型的可视化, 是数字化建模技术在各个专业之间信息交换与共享的重要途径, 直观、高效、准确的模型显示是项目顺利进行的有力保障。目前, Revit通过“剖面框”功能实现基于区域的模型三维显示, 但此功能受模型大小、硬件配置的制约, 在实际应用过程中, 还存在反复旋转模型视图、不断伸缩剖面框边界、重复操作、工作效率低下的问题。基于此基础, 论文分析了Revit模型可视化技术的应用要点, 假设出一种新的基于区域的三维模型显示功能, 并且结合Revit API开发技术, 实现了此功能的研发。最后介绍了研发的关键流程, 同时以一装配式钢结构为应用实例, 展示应用效果, 为推动BIM软件其他技术的发展提供参考。

Abstract: Visualization of building models is an important way for digital modeling technologies to realize information exchanges and sharing among different specialties, while direct, efficient and accurate model display is a powerful guarantee for the successful completion of the projects.At present, Revit realizes the 3D region model by the function of "section box".But this function is affected by the size of the model and the limit of the configura-tion.In practical application process.we need to rotate the model view and stretch the boundaries of the section box repeatedly, which is inefficient.Based on those, the key points of the application of Revit model visualization technology are analysed.Based on the development of RevitAPI technology, a new way of displaing 3D view which is based on the spatial location is proposed.Then the key technologies are introduceed and some application examples of an assembly type steel structure are demonstrated.This method provides a reference for the development of other technologies about BIM software.
