Besides being attractive for generating geometries, B-splines and NURBS are interesting because they offer great flexibility in terms of shape control. This certainly explains why most of the CAD software is based on these spline technologies. In this work, which ultimately intends to perform the shape optimization of structures, we will deeply benefit from many of the appealing properties of B-splines and NURBS, especially their efficient refinement procedures and their flexible shape manipulation possibilities. Key aspects regarding these two features are given in the following.
