INTRODUCTION Investigation one served as an introductory exploration of Rhino’s capacity to model and render architectural objects. The object to be modeled was Santiago Calatrava’s bypass bridge in Barcelona. Upon completion of the three-dimensional working model, a set of orthographic line drawings were produced, in addition to a further set of detail, interior, and exterior renderings. Several useful skills wee developed in this excercise, including the manipulation of an imported base drawing, as well as the application of materials for rendering in VRay.

INTRODUCTION Investigation two involved an exploration of Rhino’s ability to act as a fabrication interface – with both the capacity to model and produce informative data to drive a fabrication process. In particular, the investigation centered around the planar fabrication process of contouring. This involves taking a fat (3D) object, slicing it into flat contours or section cuts of a defined thickness (2D), and, after a subtractive CNC process such as laser cutting, returning it to a fat (3D) shape. The object to be contoured was an individual component of a larger wall system, assembled on-site.

Investigation three continued an exploration of Rhino’s ability to act as a fabrication interface. Using another planar fabrication strategy, an egg-crate or interlocking assembly logic, the investigation involved the design of a screen section. This design seeks to combine the divisive capability of a screen with that of a display case, creating a permeable means of product display. Limitations in cut sheet dimensions left the final product a paired-down prototype of the original design. The prototype was laser-cut from 1/8� steel and joined via a MIG welding process.

MATTHEW CARLSON initial modeled surface
INTRODUCTION The fourth investigation explored the planar fabrication strategy of tessellation systems. In this process, a curved surface is tiled or tesselated with a pattern. This patterned surface is then unrolled or unfolded, the components of which are then cut in a planar fabrication process. In this excercise, a small object (6” x 6”) was printed onto bristol paper and cut out with scissors before being assembled with glue. The object was tesselated with a hexagon pattern via a honeycomb Rhino script , written by Andrew Kudless.

INTRODUCTION Investigation four part two further examined the tesselation of surfaces in Rhino. A voronoi tesselation was used, informed by the placement of points upon an image of sea foam. A pointset reconstruction plug-in was then used to create the tesselation upon a 1’x2’ surface, which was then extruded to a 2” thickness. The unfolded fabrication strips were given a labeling system to assist in the assembly process, saving copious amounts of time and confusion. Despite this ease of assembly, adding a final border of plywood around the piece proved difficult, due to the structural rigidity inherent in the tesselation.

INTRODUCTION Investigation five part one served as an introduction to parametric modeling, using the Grasshopper plug-in for Rhino. A chosen object was examined and reverse-engineered into its basic elements. These elements were then used to inform a parametric definition of the object in Rhino. A number of variations were created from this definition, in this case that of a simple shelf. As the variable constraints for the shelf were changed, possibilities for separate or hybrid objects were ceated, ranging from a set of mail slots to a coffee table / storage unit.

INTRODUCTION Investigation five part two continued the ongoing exploration of parametric modeling in Grasshopper. Using a scyscraper as a building type, a definition was created using several constituent parameters. Additionally, a basic component, in this case a gill to allow for airflow and sunlight, was proliferated upon the building’s surface. In effect, this becomes a porous skin. The parameters defined for the skyscraper are as follows: 01. Height 02. Number of Floor Slabs 03. Floor Slab Thickness 04. Number of Support Columns + Sides 05. Bottom and Top Radii 06. Adjustable [pinch + expand] Radius Height 07. Rotation 08. Louvre Thickness 09. Louvre Aperture Width

INTRODUCTION The Fill-it Desk is informed by a design of simplicity. The design seeks to minimize wasted materials by utilizing the total surface area of a 4’ x 8’ cut sheet. The construction of the desk follows a notched or egg-crate logic, allowing for straight-forward assembly and inherent structural rigidity. The assembly logic and cut sheet nesting are presented aesthetically to be observed and appreciated, whilst consequently revealing the layered properties of the plywood material.

Additionally, the Fill-it Desk makes use of excess cut sheet material to provide a variety of supplementary components, the breadth of which is limited by the size and scale of the desk’s top surface and supporting legs. These accessories could vary in form and function, from a small shelving unit to a stool.
