MihaUrban body

I am now researching urban conditions in the model of dimensions 700 x 450m. It is revealing itself as an urban body... a house and a city at one time. The communication corridors are organic - continuous, that means there's no distinction between street, hallway, stairs, elevator, subway... they are all interiorised and intertwined with each other, there are electric cars and transportation. The anatomy of the object is similar to the living body anatomy with veins, organs and functions. So this urban body is a building block, neighborhood and a city center at one time. Beside highly internal connectivity it is also connected to outside world with subway and car traffic under the ground. Quality of living and working in such a "city" is just a state of evolutionary adaptation of humans to environmental conditions. Our environment is rapidly changing, the direct sun is more and more harmful and the daylight is disturbing factor in the digital environment, also outside air is polluted, especially on the streets with traffic smog and noise. And for experiencing the outside qualities there is still a lot of outside space in the holes of the body, from small ones to large public squares, which are a matter of choice and not the necessity.
I am also wandering about the consciousness of the body. Consciousness of the city is the place of terrible mistake, where something is going terribly wrong. Consciousness is dynamic, but can we capture it in the moment with identifiable space/object? Maybe just half real and half symbolic - object out of context, ruining the space configuration, disturbing the balance... So, I placed the cultural program in the charismatic corner of the body, where something is not right, mutation of topology is creating new condition, new exit.

P.S. I am trying to make 3d model more precise with some urban and architectural elements, but it's hardly possible with mesh mode. How can I transform mash object into surface?
