Development of an Intelligent 3D Parametric Modeling System for fhe North American Precast Concrete Industry: Phase II

Ghang Lee, Rafael Sacks, Charles Eastman, Ragnar Wessman

3D parametric modeling technology was first introduced about 15 years ago, but still only a few sectors in Architecture, Engineering, and Construction (AEC) have successfully adopted the technology in production. This paper reports the second phase of an early successful collaboration project between an industry sector, academia and a CAD vendor to develop an intelligent 3D parametric CAD system for the precast concrete industry in North America.

Keywords: parametric modeling, intelligent CAD, precast and prestressed concrete
