面向属性的参数化建模在Revit API中的应用

为改进目前构件级建模过程存在的效率低问题,提出面向属性的参数化建模过程.此方法使建模师不需要重复传统建模操作,通过设置模型属性参数就可以实现相关数据的统计和计算从而快速建模.以球面网格结构为例,将参数化建模思想融入到Revit二次开发技术中,借用VS开发工具实现三维模型的快速生成.在操作时,用户只需通过用户界面输入矢高、跨度和环数等结构参数即可以完成模型的快速建立.通过此程序,还可以实现肋环形和施威德勒型2种类型的选择,实时监测设置的参数是否满足规范要求.

Application of attribute oriented parametrization modeling in Revit API

To improve the low efficiency problem of the component modeling process, an attribute oriented parametrization modeling process is proposed. By the method, the model architect do not need to repeat the traditional steps. By setting some property arguments, all the related data can be calculated to realize the rapid modeling. Taking a spherical grid structure as the example, combining the parametrization modeling with the secondary development in Revit, the rapid creation of a 3D model is implemented by the VS development tools. During the model generation, the user only needs to input some parameters through user interface, such as vector height, span and ring number. By the program, the structure types can be chosen between the ribbed type and the Schwedler type. It can also monitor whether the parameters meet the requirements of the specification at real time.
