Dodecahedron

Agregated Assemblies

Faces: 12 Polygons Edges Per Face: 5 Dihedral Angle: 116.565

Dodecahedron Construction To construct the polyhedron, I used the Dihedral Angle to form the angles between faces, Dihedral Angle

3d Dodecahedron

The scale of the origional face determines the scale of the dodecahedron.

Inscribe Cube

Division of Cube Faces

Extrusion of Faces

Reveal of the Cube In each opposite face of the cube, sectionsi of the dodecahedron are removed to expose the cube and a surface to connect to rationalize into x,y,and z connections.

I tried to inlay many secondary shapes, the one I decided was most successful was a cube. The cube allows the geometry of the dodecahedron to be controlled in along 3 axi, x, y, and z.

Aggregating the Component

Alternate Aggregation

Designing the Egg-Crate One of the issues I had with eggrating, was due to the sharp edges, many planes not continuous through the form. Also, many of the profiles were left too weak to be routed. The greater number of divisions the more pieces were left discontinuous. Various Rotatoins were also tried.

Modified Egg-Crate

2 x 2 EggCrate Minimized down to 2 x 2 the profiles are solid, and strong enough to be routed. One of the directions is missing, the shape is meant to be identical about x,y,and z.

Component Assemblies

3 Faces of Assembly One weakness of this stage is that only 3 of the faces are used to build the component.

2 Different Pieces A second weakness of this stage of the component, is that it uses 2 different pieces. Pre-aggregation, I feel that there should be only one plate to generate the component.

Modified Egg-Crate

Single Plate In this generation of the component, 6 identical plates generate the component. This creates a much more straight forward assembly process.

Component Assemblies

6 Faces of Assembly The left image becomes a theoretical assembly process. Through further exploration through phycial model, the process on the right is revealed. With three of the pieces locked together before coming tother, no single surface can be removed.

Small Scale Aggregation If the components are joined before egg crating, the plate orientation does not rotate with the component, and it is no longer identifiable as a single entity.

Plate Connection The plates that are highlighted transverse 4 intersecting divisions. On either side the plate is not continuous across all six. This creates a strong tie between the component and the connection.

Component Aggregation

Merged Plate Aggregation

Straight Connection The Straight connection requires the plate to be flipped and rotated, but the benefit is the orientation is the same on both sides,.

Plate Component The Eggcrate component was minimized down to a single surface. Collectivley, they form the origional component.

Angled Connection The angled connection is purley a mirror about the edge. This creates a rotation that causes a shift in the origional x,y,and z axis.

Straight Plate Connection

Straight Aggregation Very Regular patterning, continuous, Infinitley Aggregates.

Angled plate Connection

Angled Aggregation Irregular Patterning, dis-continuous, must be modified to continue to aggregate.

Highlighted Intersecting Plates In the angled aggregation, some plates begin to intersect. To solve this, the origional single plates are reintroduced.

Larger than a House, and Smaller than a Building

Seating Aggregation

The first viable scale study was as a seating element. The next step was to modifiy the aggregation to utilize single plates to perform its task better. The freedom of the system allows it to be easily modified to fit a different program. For this aggregation, function dictates the form the it takes.
