［摘要］参数化技术因其在建模上卓越的可调性和对复杂形体建筑良好的适应性，日益成为建筑设计的重要工具。以Rhinoceros平台的Grasshopper软件为例，对可视化节点式参数化建模方式进行简要介绍，结合正放四角锥网架范例和某体育场工程罩棚结构建模过程，给出参数化建模在空间网格结构建模中的基本应用思路。实例表明，参数化建模可大大提高工作效率，所建模型可快速修改调整，且可视化节点式参数化建模方式技术门槛不高，可推广使用。同时，也应看到参数化建模在处理复杂形体结构局部部位上存在一定局限性，需辅以少量人工干预。

Abstract: Parametric modeling technique has become more and more important in architecture design area due to its extraordinary flexibility in model establishment and adjustment. Based on Rhinoceros and Grasshopper software application, it gives an introduction on parametric modeling technique. The basic concept of employing parametric modeling technique in space frame structures is illustrated with two sample cases, a square pyramid space grid structure and a roof structure of a sports stadium. Example shows parametric modeling not only increases the modeling efficiency but also makes the model easy to be modified. The exploiting of nodal programming tools such as Grasshopper in Rhinoceros dramatically reduces the difficulty in parametric modeling. Some disadvantages should be noticed when dealing with complicated shaped structures where a few manual operations are required.

Keywords: parametric modeling; space frame structures; Rhinoceros; Grasshopper
