THINK It is a time when digital and machines are used. This time will continue to evolve and change. Accordingly, architecture must conform to the times.
PAVILION CASE STUDY It didn’t use the GRASSHOPPER only RHINO because then I didn’t know how to do GRASSHOPPER I want to make this PAVILION again throught this class WITH GRASSHOPPER

PROJECT ANAYSIS The project was for the penthouse offices of an investment group in green building and clean energy technologies(CChange). The design drew from our prior sculpture, In the Shadow of Ledoux, 1993, and the Galerie Miran, 2003, proposing themilling of all elements of the interior from sustainably-forested spruce plywood using numeric command machines: information carves renewable carbon-absorbing resource
CAD_Isometrie.jpg
An office refurbishment that relentlessly deploys numeric command machining of sustainable plywood to evidence the versatillity and efficiency available via CAD-CAM design-build processes. The project displaces the combinatorial process for a seamless aesthetic emerges from these processes.imbuilding the design with a curvilinear continuity at a detail and spatial level. In a material sense.the project assumes a radical environmental agenda. using a sustainable and carbon-absorbing raw material(forested spruce). translated efficiently into refined and functional elements via dexterous low-energy digital tooling.

The project essentially comprises two planes - the floor and ceiling. both of which are articulated as continuous surfaces inflected by function. The curvilinearity expresses both the digital genesis and the seamless fabrication logic. with the architect providing actual maching files to the fabricator. 5
DESIGN COMPUTAION
UNITARY FABRICATION LOGIC All visible elements of the design, except the glass. have been fabricated as stacked sectional elements cut from flat plywood sheets by a single 3-axis numeric command milling machine. The ceilings,walls,floors and static fumiture have all been made as striated ply laminated elements, with functional elements such as ventilation grilles,light pockets,and door handles formed directly by milling the mass of wood.

This unitary fabrication method offers a remarkable streamlining of the typical multi-trade assemblage techniques of extant lateindustrial protocols,with evident economies of labor,materials and logistics. Despite the formal complexity that such process allows, a radical economy is offered in a single fabricator with a versatile digital tool being able to execute the project in toto.tal agenda. using a sustainable and carbon-absorbing raw material(forested spruce). translated efficiently into refined and functional elements via dexterous low-energy digital tooling. The project essentially comprises two planes - the floor and ceiling. both of which are articulated as continuous surfaces inflected by function. The curvilinearity expresses both the digital genesis and the seamless fabrication logic. with the architect providing actual maching files to the fabricator. 6

SCRIPTING/ MACHINING PROTOCOLS It was imperative to streamline the actual milling process for speed and economy. This issue was compounded in that the lowest tender came from a millwork fabricator with a single 3-acis CNC machine. This dictated that we develop milling protocols for the complex-curved edges of the plywood sheets in order to find the most elegant ‘weeping’tool paths to cut the parts with macimum effi ciency. to facilitat this, we developed a series of scripted protocols that would analyze the surface geometry and automatically divide th parts,depoying toolpaths in lieu of acual geometric information.

COMPUTAION / GENERATION SCRIPTING/ MACHINING PROTOCOLS As architects,we handed over actual milling files for fabrication,already nested onto plywood sheets to minimize waste,which were the actual cutting instructions then issued digitally to the numeric command machine. These highly abstract machine instructions displaced the usual representative precepts of architectural production,but in fact we deviloped a machinic ghost of the final form,never modeling an accurate orginal! Well over one million linear feet of cut were issued,a shift in the base protocol of contraction logic,the architect now fully in control of every detail via fabrication code. Machine-age manufacturing logic shifts to digital fabrication processes.

Ultimately we devised automated algorithms for generating actual milling files,passing from design to fabrication seamlessly and with high tolerances and extremely low percentages of error. 8
CONTINUOUS-SURFACE FORMALISM The formal vocabulary emerges directly from the continuous marching process,where the numeric command machine executes curved cuts with equal precision as straight lines,essentially indifferent to the complexity or number of cuts. There is efficiency in maintaining surface continuity,large and highly accurate prefabricated arts quickly installed on site without the need for multi-component assembly. This is manifest in benches that curlout of floors,or reception desks that emerge as inflections from the general field. The continuity of surface,in fact assembled into an apparent unity from many highly accurate customized parts,is the formal extension of the machining logic,challenging the component-assembly aesthetic of mchine-age fabrication logic.

COST REDUCTION One Main uses sustainably forested Finnish spruce ply with non-toxic water-based glue. The 10,000sq ft (1000m2) project nested onto 1200 sheets of 1.5� thick 4ft x 12ft ply, milled locally by a single 3-axis milling machine. dECOi provided the actual tooling paths (over 1 million linear feet of cut), with no plans or sections, just 3D instructional files. Wastage was about 10%, pulped and recycled.

ACCURATE EXPRESSION The client asked that the work chairs be purchased for liability reasons, but all shelves, desks, benches, storage units, etc were accepted for direct fabrication in plylam via the same method. Ultimately we devised automated algorithms for generating actual milling files, passing from design to fabrication seamlessly and with high tolerances and extremely low percentages of error. Well over a million linear feet of cut were issued, yet the machinic process was essentially error-free and highly accurate. Assembly proved relatively straightforward given the accuracy of the milling, and we enjoyed the elegance of the emerging forms. 10
