摘要:现阶段Revit网架建模存在很多弊端。常规建模方法由于杆件数量过多导致建模工作量繁重, 难以检查修改。应用体量模型建模速度虽快但整体模型不够准确, 构件参数不能单独设置。为了提高设计效率、提升建模精度, 本文采用Microsoft公司的visual studio2015开发平台, 对Revit进行二次开发, 编写网架自动化建模程序。本程序通过读取LOG文本加载焊接空心球节点族和杆件族, 快速、方便、准确地生成Revit焊接空心球网架模型, 适用于非曲面标准网架。生成的网架可以按照LOG文本更换对应构件的种类, 网架整体尺寸与实际情况相符, 极大的较少了设计工作人员的工作量, 提高了设计效率和建模质量。

Abstract: There are many drawbacks in the present modeling of the grid structure in Revit.Due to the excessive number of components, the conventional modeling is heavy in workload and difficult in to check the errors and to modify them. Applying the volume modeling can be in speed, but the overall model is not accurate enough, and the component parameters cannot be set separately.In order to improve the design efficiency and the modeling accuracy, this paper uses Microsoft's visual studio 2015 development platform for a secondary development of Revit to prepare a grid automation modeling program.This program can generate the Revit model of the welded spherical joints grid quickly, easily and accurately, through reading the LOG text to load the welded hollow sphere joint family and the member family.This program is suitable for the non-curved standard grid of welded spherical joints.The generated grid structure can be modified by the size of the corresponding components according to the LOG text.The overall size of the grid structure is in accordance with the actual situation, which greatly reduces the workload of the design staff.
