We used Rhino + Grasshopper to develop the geometry of the Memory Cloud.  Beyond qualitative spatial and aesthetic criteria the tools were used for developing quantitative data sets for the lighting purchase orders and assembly inventories.  The waffle structure of the diagrid canopy was developed using FEA software at Insight Structures and feedback from that analysis drove the varying depth of the profiles.  The notches were calibrated based on a full scale prototype that tested the material welding.  We especially benefited from the use of the Lunchbox plugin for Grasshopper developed by Nathan Miller of CASE, Inc.  The diagonal structure tools created clean data structures that retained their organization as the geometry was projected into the cloud.
