Assessment of the Generative Design The Generative Design Phase takes as inputs the fragment, the optimized position and extension of the clamp components, and the outer envelope of the fragment and clamps achieved with respect to the point of view of the observer. The clamps are considered as preserved geometry along with the base components of the support which are designed inside the intersection between the outer envelope and the mounting plane. Since the supports are intended to be screwed to the basement, the base components are three hollow cylinders, as reported for both the case studies in Figg. 6(a) and 6(b).

Obstacle geometries are the fragment, the extruded outer envelope, the obstacle connectors related to the mounting of the screws, and the basement desk. The outer envelope is necessary to satisfy the aesthetic requirement of minimizing the visibility of the support from the observer viewpoint. Indeed, with these constraints, the support can be generated almost entirely behind the fragment, as reported in Fig. 7.
