Olympic Design by DS/Bentley/McNeel

The Beijing 2008 Olympics Stadium, the London 2010 Olympics Aquatic Complex, and other olympics facilitiies were/are designed by the design firm Arup Sports of England using Dassault's Catia CAD software together with Digital Project from Gehry Technologies. They used Bentley's software for the design of the National Aquatic Center "water cube."

A reader tells me that:

Arup apparently they also used Rhino, combined with internally developed software, for some engineering. Arup makes a oblique reference to this [PDF], saying that they developed a computational design and optimization toolkit for Rhino, for a steel spaceframe stadium roof.
