Body to Grid Relationship

Hello,

I am very new to Grasshopper, using it for a studio course in my architecture program. At the moment, I am trying to create a relationship between a grid and the human body. I've made an attempt, which I've attached below in a rhino and grasshopper file. I constructed the grid by intersecting planes. However, it doesn't seem quite right. Ideally, as the grid would be scaled to the body by a ratio. For instance, if the body is 6' tall then the horizontal planes will be 1.5 the height of the human. I'm also interested in how the grid might change when more human bodies are added to the equation (more people, the grid expands and scales to the number of people), but have been unsuccessful so far.

Any help or suggestions would be appreciated.

Thanks!
