New Algorithm Helps Architects Create Complex Curved Structures in Minutes
A new algorithm is transforming how architects design lightweight curved structures. It uses NURBS surfaces, which many designers already rely on in CAD software. As a result, it cuts computing time from 90 hours to just 90 minutes on a standard CPU.This tool makes gridshell design faster, smoother, and more flexible. It also opens the door for more creative work.
Why Gridshells Inspire Modern Designers
Gridshells use intersecting curves to form strong and elegant shapes. They often appear in stations, courtyards, and plazas. For example, the British Museum’s Great Court and New York’s Moynihan Train Hall both use this style.Designers value these structures because they cover large areas without columns. However, they have struggled to create new and unusual forms due to time and technical limits.
Solving Old Challenges With New Speed
Researchers Masaaki Miki from the University of Tokyo and Toby Mitchell from the U.S. developed this improved method. Their algorithm finds the best geometry for a gridshell, even when the design is highly complex. In addition, it maintains structural strength and reduces the heavy computing power once required.Earlier versions faced two barriers. They had trouble with irregular shapes and took far too long to run. The updated tool removes both issues, making advanced form-finding more accessible.
Smarter Workflow With NURBS Integration
The method works directly on NURBS surfaces, which offer smooth and precise geometry. Therefore, it fits naturally into Rhinoceros, a popular CAD platform. This workflow lets architects create stable shapes using simple tools and everyday hardware.The team also aims to expand the method to timber gridshells. This step may further broaden material choices for future public spaces.
