Summary of my pitch
Parametric design allows architects to obtain design options that leads to more reasonable design. Without software’s help, the architects have to manually look for an optimized solution and they might miss possible options. This project focuses on creating a truss roof. To enhance the versatility of the design tool this study proposes, the size of a roof and members, and the number of sections and waves are selected as a parameter. The number of members and connections and the volume of members can be obtained as an outcome.
Users
The design tool this study suggests is expected to be used by architects.
Needs
Architects spend a lot of time to find the best design solution. In addition, traditional design method faces limitation to explore more options. The design tool contributes to the reduction of working hours and enables users to be exposed to many design options.
Inputs
For the flexibility of the design tool, the required inputs are as follows.
The position of a reference point
The length of roof in X and Y directions
The number and amplitude of waves
The number of divisions in X and Y directions
The benchmark of members
Logic
Based on the inputs, the tool creates a truss roof. Also, using the generative design function in dynamo, some alternatives and their data such as the total volume are provided.

Outputs
This design tool provides three outcomes shown below.
The volume of members: Lager volume leads to higher material cost.
The number of components: More components require longer time to assemble them on site, which causes higher labor cost.
The number of connections: More connections of components need more bolts or welding, which results in higher material and labor cost.
