For this module, I decided to modify the Twist parameter (Top Rotation) because it is the most visually impactful parameter to change and can generate very original building shapes. For the given forms, I chose the Flying Chevron Arc because a large part of its geometry is circular, meaning a change in twist will not significantly warp the solid form or drastically alter the floor area value, keeping it within a stable and predictable range.
As for the cusom shape, I designed an eight nodes solid using 8 reference plans that can help define a pointy rectangular shape. I also varied the twist parameter for this one in order to visualize more the changes, but as the output values vary more (non circular shape) I incremented by a lower angle.
Dynamo Parameter Change:
In Dynamo, the main component was constructing a custom node that takes the element and the list of values to test for the chosen parameter (twist), and outputs the requested metric values (GFA,GSA ,GV). I chose a different output structure than the one provided in the modules, as I found it more efficient to retrieve all values in a single run as a complete table. Using this approach, I input the geometry and the list of values I wanted to test, then exported the results directly to an Excel sheet, with a separate sheet for each structure.
Note : All the chosen parameters and increments were chosen so all the limits of the project were respected using SI units.
Point to Ponder:
The advantage of exporting values to Excel is that it is a powerful tool for handling large amounts of data in an organized and accessible way. The exported data can also be further analyzed using MATLAB or Python for more advanced studies. Additionally, Excel is a familiar and widely used tool among both engineers and architects, making it easy to share and interpret results across disciplines.
