Computer Aided Geometric Design (CAGD) is a crucial technique in structural anaysis and design optimization. The CAGD can be categorized into several geometric definitions such as Coons patch, Bezier surface and NURBS. It can be effectively used to generate the FE mesh for continuum and discrete structures. The utilization of CAGD is powerful in shape optimization. For an example, Figure below shows the process how to control the free-form structures using CAGD.
