As a modullar project, when I saw her design, we decided to help each other. So I model her Idea in GH, and afterwards we do some shape / sun / shadows analysis to the model parsing the results to external files.
She has the law in ther mind, but she didn't know about GH, so I started a parametric model with the idea she had and this is the result of introducing a predefined law with several parameters in GH.
Of course the recursivity of this proccess was the main reason for using GH because we could adapt the shape and the law to several procces changes or evolution of the idea.
