Manipulating results by testing a range of inputs or "flexing" the system we've

created and gathering data for further analysis from tools such as Autodesk Ecotect.

The process of flexing the model allows us to determine the range of inputs and outputs that

are possible for a given system.

Difference in need of the openings

can be observed depending on the

type of material used.

In the final step systems are rationalized, output files for manufacturing to

create physical models and simulations.

- Extract Geometry & Planarize Curved surfaces

This leaves the skin with the visual and performance characteristics

intended but simplifies the system.
