Abstract
We present a design model for a (grid)shell that is an assembly of 3D components (‘rational-voxels’) fabricated from planar/developable faces. This rationalization was achieved thanks to the geometric properties of principal patches arising from a Triply Orthogonal system of Surfaces (TOS). By using such a system we were able to generate a curvilinear coordinate system where the coordinate lines are principal curves on the respective surfaces in the TOS. Next, generate 3D components (voxels) where each voxel is a curvilinear cube where its sides are principal patches, and its edges are principal curves obtained by intersecting two neighboring surfaces from each of the three families in the TOS. These voxels are then rationalized into rational-voxels having planar/developable faces and straight/planar edges. The design model allows for five degrees of design freedom for choosing: (1) the shell-slice type in the TOS, (2) the shell-slice thickness, (3) the voxel-assembly method, (4) the rational-voxel type and (5) being either a solid or a hollow voxel-assembly. A design to build process of a large scale pavilion is presented as a demonstration of the proposed design model.

The realized prototype was the result of work done within the framework of a workshop for the master students at the national school of architecture and landscape in Lille. The supply of materials, production, and transportation of the pavilion was funded by the school. The pavilion was exhibited the 11th of June 2022 at Bazaar St-So during the 10th edition of the “braderie de l’architecture”.
