The angle between the "α" and "β" planes is divided into equal parts. We identify the planes of arrangement of the intermediate cutting planes which, in turn, generate elliptical tracks on the hyperbolic surface.

G
Each ellipse is divided into an equal number of segments, to allow the interpolation, through points, of a rhumb curve “G” lying on the surface of the hyperboloid. By repeating this operation with constant pitch, we obtain the other generating curves.

Given the dimensional constraints of the printer, the hyperbole "I" lying on the floor Y and makes a revolution around the axis "z" resulting in a hyperbolic hyperboloid. Chosen the cutting plane "β", with a different inclination from "α", it identifies an elliptical track "E" in the intersection with the hyperbolic surface.

Through vertical symmetry, we get symmetrical slats.
We define the solid ribs through a bidirectional offset of rhumbs surfaces and subsequently inserting two cutting surfaces, one at the top and another at the base, obtained through a loft of the head sections of the ribs. These surfaces truncate the terminal nodes to obtain flat silhouettes at the ends .

A hyperbolic surface is modeled from the offset of the previous one and intersecting the ribs which, thus, are visible both outside and internally. To this surface it is given a minimum thickness that allows a translucency effect.

We make the intersection between the ribs and the intermediate surface to obtain the traces, corresponding to the blank fields. The drawn shapes are extruded in both directions (internal and external) obtaining the solid elements to be subtracted from the total volume.
