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
