Duygu Kirisoglu // Jesús Zabala The main idea is based on the usage of both sides of the bench. To do so, the bench has been divided into two in the middle. The form of the bench is generated mainly with plug-in called t-splines which allows to manipulate the surfaces smoother. In order to do that all the surfaces are converted to t-spline surfaces. Commands in t-splines such as manipulator, grip selection, smooth toogle etc are applied on the object. After the design is completed all surfaces are converted to rhino polysurfaces in order to make the ribs of the waffle structure. Contour command is applied in both x and y axis with different distances. Thereafter,  to have the notches on the intersection of the ribs’ surfaces, a grasshopper skript is used. Finally Project cplane command is applied on the surfaces to get all the pieces on the same level to print in lazer cutter.
