The Advances in Architectural Geometry Conference Geometry lies at the core of the architectural design process. It is omnipresent, from the initial form-finding stages, to novel manufacturing techniques, to the construction, and to post occupancy monitoring. But the role of geometry in architecture and engineering is also continuously evolving. Geometry increasingly plays a role in modeling environments and processing sensing information. Modern geometric computing provides a variety of tools for the efficient design, analysis, and manufacturing of complex shapes. Besides descriptive geometry controlling form, algorithmic processes play a crucial role in integrating disciplinary input. On the one hand this opens up new horizons for architecture. On the other hand, the architectural context also poses new problems to geometry. Around these problems the research area of architectural geometry has emerged. It is located at the common border of architecture with applied geometry, computational design, mathematics, and manufacturing. Advances in Architectural Geometry (AAG) is a conference where both theoretical and practical work linked to new geometrical developments is presented. It involves architects, engineers, computer scientists, mathematicians, software and algorithms designers and contractors. We aim at connecting researchers from architectural and engineering practices, academia and industry. AAG has become a reference both in research and in practice and is supported by the direct participation of the most renowned architectural design and engineering offices along with research laboratories. The symposium is a biennial event. It was held first in 2008 and 2010 in Vienna, 2012 in Paris, 2014 in London, and 2016 in Zurich.
