中文摘要
      为改变当前主流的基于约束的参数化建模方式复杂、建模效率低下、用户很难掌握的情况,从操作记录出发设计了一套基于操作的钢结构参数化节点制作系统,讨论了基于操作的参数化建模与基于约束的参数化建模在建模方式、系统开发、底层逻辑等方面的区别,介绍了操作实现的原理,研究了参数化节点中逻辑信息的写入,实现了利用工业基础类文件来储存参数化信息的方式.基于操作的参数化建模与非参数化建模在建模方式上基本一致,与基于约束的参数化建模相比提升了参数化建模效率、实现了参数化信息的共享、减少了相似节点的重复制作工作量.最后用实例验证了基于操作的参数化建模方式的优点.
英文摘要
      To change the situation that the normal constraint-based parametric modeling method is complex, and the modeling efficiency is low, which is difficult for users to master, a parametric steel joint system based on operation was designed. The difference between operation-based parametric modeling and constraint-based parametric modeling in modeling method, system development and the underlying logic was discussed. The principle of operation was introduced. How to write the logical information into the parametric joint was studied and using industry foundation class(IFC) file to save the joint was realized. Operation-based parametric modeling and non-parametric modeling are basically consistent in the modeling method. Compared with constraint-based parametric modeling, operation-based parametric modeling’s efficiency is improved, the parametric information is able to be shared, and the redundant work of developing the similar joints is reduced. At last, the advantages of operation-based parametric system were introduced by examples.
