For our model we elected to do a simple, acrylic, laser cut with a MDF base designed to accommodate led up-lighting.

However, to develop new skills, we decided use Grasshopper as much as possible to prepare the model for fabrication.  We made two Grasshopper scripts to achieve our goal.

The first one used contour to divide our mesh from Maya and lay it out on a flat plane.

Our second script created an offset on every other layer; initially, we were hoping to have every other layer with a hollow core. However, the complicated geometries made it unwise to use our second Grasshopper script.

Unfortunately our Maya Mesh did not have a clean set of unions, so we had to go back by hand and trim each of the overlapping curves.

We laid out a duplicate of each layers subsequent layer on top of it as a score layer. Then, to reduce cut time, we trimmed the score layer to only exist on our cut geometries.

Also, to make assembly easier, we will submit the acrylic on top of a sheet of cardboard and request that the pieces are left in the sheet to make orientation of the 240 similar pieces easier.


This tool analyzes the torsion of a curve at any given point. Simply set the curve to a curve in your rhino model and adjust the slider to the point that you want to analyze. As you move the slider back and forth you will see the point move on the curve in your Rhino model. If you hover over the “T” output, you will see the value of torsion for that point.

The RE:pH – Coastscraper is an eVolo Skyscraper Competition entry from 2011 done by Gary Kellett from the United Kingdom. Due to the drastic increase in CO2 that the ocean’s surface must take up, our oceans have been increasing in acidity levels not experienced for at least 400,000 years. The high levels of acidity harm marine ecosystems. The Coastalscraper functions to pump fossilized Coccolithophores (white chalk) into the ocean to increase the pH levels of the ocean and, ultimately, mitigate ocean acidification. The entire Coastalscraper acts as a mobile chalk excavator and refinery, scraping The White Cliffs of Dover, England, known for its vast chalk deposits. Once the chalk has been refined, it is stored in vast silos within the building and then pumped up towards the ocean surface through Deep Sea Plume Jets attached to the Coastalscraper via pipelines.

Kellett’s Coastalscraper inspires me with the idea of building as machine with the purpose of earth revitalization. The form of the building reflects its purpose on the exterior rather than hiding the true function within standard forms. The exterior expressions of the building’s various functions allow for an intuitive understanding of the program layout within the structure. I also find variety of scale within this project; some portions seem enormous next to a human figure in order to awe and reflect the magnificent global impact of this project while other portions seem appropriately scaled to a human for functionality and comfort for occupants.
