Parametric Freeform Modelling: Facade Panelling, Structural Framing

Hi, I would like to know how to model the structural frames based on this form and achieve the panelling patterns with this organic form. I know it probably created with lunchbox quad panels but not sure how to split the surface into different areas with different panelling.

I have created a similar form roughly but not sure how to start. :slight_smile:freeform parametric model.3dm (904.9 KB)
