The story continues

Thanks to a good working session with my tutors I finally have a modeling approach that gives me the control I want. Here is a first experiment with it finding out how the shadow might look, made using 'Project' in Grasshopper. (Sun movement is reverse from natural btw.)
In this model I can set radius, height & width of the cell wall and angle of the corners in the bottom row of the structure. It then determines the nr. of cells around and in height on its own to make a fitting roof.
