introduction
Form-Finding Parametric modeling means efficiency and precise. It simplified the process of form generation into digital scripts, facilitates the popularization of remarkable forms. However, the origin of parametric design, in our understanding, is not just the logic and program. Similar to the relationship of tools and craftsman, the innovation in thoughts and creation of methods is the initial motivation. What we are exploring for is the basic inspiration of design. We are not seeking technique but a way to link the digital method and reality world. Face with the battlefield of Parametricism, architects has some kind of similarity with the people who first leave the cave in innocence era. We re-explore the character of material in new shape; re-create tools to test the potential and limitation of matter and form. The possible design quality behind script is what we aimed to achieve.
Work In a System Coordinate with the parametric working method, we desire to mold a system which sysnthesis the form finding process and material articulation. This systematic gesture can be treated as the base of our machine aesthetic. Such value will be coherence in our design of touch stone, spatial model, culture model and faรงade prototype. In this system, tension and compression of material, visual and private quality of space will be represented in the media of force and field. They concentrated in the flow of our faรงade and the altering space enclosed in it.

Parametric design has different meanings ranging from social to mathematical connotations, mostly related to a measurable variation. The term “parametric design” associates the general action of the design to the adoption of “parameters”. …, the word “parameter” refers to data that affect a situation. The use of this term in computational design came up … with the emergence of methods to describe curves through parametric equations. Rodrigo GARCIA AL VARADO, Jaime JOFRE MUÑOZ
Touchstone The start of making objects in regarding of precedent studies. The defining moment of the studies give a hint to the touchstone design and a lot of later design is directly reference back to the touchstone, which we consider this is an important stage and objects in our project.

1.1 Precendent Studies In this studies, we look at the relationship of the exterior and the interior as well as the use of material in respect to this aspect. Casa da Musica has a dominant exteriority sit in Portal Portugal. However, the form generated in respect to the surrounding context and also the program arrangement and materiality emphasis this gesture. The central auditorium act as a core of the building and it address the plaza which is the joining point of the city grid. Each of the opening response to different view of the surrounding, such as the small auditorium, considering as the main function of the building, facing the cemetery where the architect consider it as an important landmark. The drawings shows and explore this idea generated by the building.

1.2 Recipe
The interest in this project for us is about how the Casa da Musica addressing the view through spatial function and architectural arrangement. The view connect the interior space with the exterior and shows which part of the city is important to the function, occupant and the architect. The overlap view from main program (auditorium) through other programs (eg, education space) eventually outside shows the strategy that tighting and emphasizing the relationship between the core and the exteriority. The recipe is base on this logic to address desire view and avoid some views. The information you get from different view point is different, this is similar when you are in the Casa da Musica auditorium, seeing different window you will get different information in regarding the spatial function and views behind.
A. Choose base point inside a volume (representing inteior factor) B. Create points outside the volume (representing exterior factor) C. Connect the points to address views D. Make the connected line with tube solid or void for the volume The three pieces was created sperately base on the recipece and rules that was setup. It all address the relationship between the standing point and view point. The view point is adjustable so that the shape can modify towards a desire view.

Difficulty we face to make this touchstone is all focus on the double curved surface of the volume. We are attempt to smooth and continue suface for the twisted box while precisly placing the openings on the surface as well as the desire thickness of the box. 13

Panellization
At the first place, with the lack of understand to the CNC machine and materiality we decide to use a more easier method to achieve the double curved surface. The panellization system can compose the double curved surface easily, but fix angle and strictly join can not reflect the formation of a force twist the box naturally. The result is not what we expected, the lacking of proper joint system and consideration in material thickness make this approach fail.

After the form work molding, we are very interested in the pillow surface that we managed to create. We decide to explore more on how can we create variation in one mold and asking ourselves, are we able to control the double curve surface apart from using the CNC milling method. We make formwork with ply wood as it is a tiling system so it is able to stack up to make a wall. For the surface, we use a pin system to generate the surface and openings. The pin is able to adjust the cliping distance and the grid on the blue foam is use to locate the pin. This for a simple parametric system for the mold. Although this is considering as a parametric mold, the blue foam is pin through and no longer reusable. We decided to design a mold that is fully parametric and precise.

1.3 Digital Crafting
by Ching Yu Liao
Since industrial revolution, the mass production age emerged. The uses of machine to produce replicated products dictate the world. Everyone is using similar item produced by different manufacture. The beauty is about speed and minimal of crafting. Like other industry, architecture also brought to a new era by this phenomenon. Architecture is designed and produced is a similar way all around the world by taking the advantage from the machines. This brought architecture to the age of International Style. Architecture goes closer to an art of producing and more far away from an art of crafting. “Craftsmanship” started to fade away in the field of architecture. However, the technology become more advance and give us the opportunities for “digital crafting”. Nowadays, everyone get access to CAD software and it is become more users friendly. Ideas can be simulate and develop in virtual space, any three dimensional form can be achieve even without physical limitation. As a result, ideas and imagination can be limitless but this brings us back to an essential question: How can it be produce as a physical object? The emerging of machines such as 3d printer, laser cutter and CNC machine provide a medium for digital craftsman to become a real craftsman. CAD designed object can be produce easily and become more complex, this arose another problem: Are we designing? Or the computer itself designs? Nowadays, many artist or archi-
tects rely on the constraint provided by the software to design, they produced similar objects and architecture. Those object are complex and stunning at the first glance but when more and more similar objects or architectural pieces are produced following similar rules and using same software it is not a health trend in the realm. “Aesthetic” is achieves by slight adjustment in a similar system and spaces is designs by adjusting to its best outcome in the virtual space. This is danger for designer approaching another “international style” era not only in architecture but also in other realm where products look alike in terms of spatial effect, construction method, formal experience and even materiality. In addition, information transfer is lightning fast today it is very dangerous designers are overcome by information and forget the essential meaning of design (to achieve aesthetic as well as function) and craft (the art of making process). Not to be overwhelm or control by the system or the software, as designer we should be able to design a system to design. It is the system and logic it make sense for a design, each system and logic is specific behind a project rather than duplication and alteration. This approach will bring us back in similar to designing by pen and paper and also bringing us to a digital crafting age. Crafting is a process of making, testing and trial, the repetition of the process and the perfection through the process is the art of
crafting. In digital crafting, similar approach is taken with the help of machines, in today’s technology it is easy to make, test and remake as an individual designer. Therefore crafting can be re-alive after a long period of ignorance by some designers. The crafting approach in designing is more realistic and human rather then come up a form and thinking of how to make it. The main idea is the development of taking account the making method alongside with the design process to gradually approach to perfection so that the final outcome becomes a crafted object. Designing in regarding to digital crafting is not about producing a complex stunning but meaningless object. The fascination is the idea and story behind the object and the values of the outcome in terms of cultural, contextual, spatial and technical. Designers should take the “digital crafting� approach in their designing process so that the value and meaning is different and unique. To conclude, designing with the help of programs and software is convenience but it is also a trap if the thinking behind using the tool is not clear. In the future, it is more towards about designing a system behind a design. It is becoming more risky when the computer and program become powerful, even designer can press a button to come out a design or software that can analysis the digital model and create the most efficient joint system by inputting desire materiality and
fabrication method. However, keeping the digital crafting logic in mind the outcome would be consider as art for mankind.

Society can only evolve with the simultaneous ordering of space. The elaboration of a built environment, however haphazard, precarious, and based on accident rather than purpose and intention, seems to be a necessary condition for the build-up of any stable social order. Patrik Schumacher
facade as craft The development of logic for the building as a craft in terms of facade, spatial and materiality. The brief was carefully examine with the urban situation and the proposal of integrating business mode with Sofitel as well as the insertion of a market lane to engage public users. The spatial and and technical idea was develop at the same time refering back to the touchstone.

2.1 Spatial model
The soft transformation of the surface in touch stone inspired us that through the interaction of forces in the space architectural form can alter its character to address the issues of what it is facing. The motion of surface plays like the clay in craftsmen’s hand. Can react into the shape we want.

A craft is a profession that requires some particular kind of skilled work. In a historical sense, particularly as pertinent to the Middle Ages and earlier, the term is usually applied to people occupied in small-scale production of goods. The traditional terms craftsman and craftswoman are nowadays often replaced by artisan and rarely by craftsperson. - http://www.wikipedia.org/

Strategy addressing the site issue
Craft Victoria is located in the southeast corner of Melbourne city, a relative quiet site. The connection of it is monotonous (only can be accessed from flinders lane). For developing the potential of the site, we treat craft victoria as a market corridor connect from Sofitel shopping center to flinders lane and finished in spark lane. We wish to use the integration of craft victoria and the district environment to enhance the cultural atmosphere of the site. The leaping bridge will become the landmark of crafting culture.

Timber waffle modle provide a precise description of the space, this gives us a testing ground of what do we looking at and what we don’t want. The solid and non controlable spatial formation weaken the expression of interation of force developed from the first spatial model. This lead us to think of what can we do about how to make it precie at the same time fluid. 40

2.2 Crafting paramatric facade by Chuncheng Zhang
Nature’s main process of creation is morphogenesis, which means splitting one cell into two cells. This process has no thoughts and no central co-ordination. These cells can either be identical and distinct with each other (Lewis Thomas, 2008). In microscale, it is DNA making judgments of the cell about where to fold and where to change. DNA is a basic organic compound, but we can simples treat it as a script too. What happened in the cell is when the micro environment changed, it will change the status of the chemical inside the cell, and such input will active different fragments in the DNA and then these code of inheritance will alter the direction and transformation way of next self-replication. The description of morphogenesis above interprets the generation process of natural product. It has the basic idea of the basic elements we need in a form generation system: transformation rule that describe where to change and a fundamental way of how to change. The simple example is that when we fold one sheet of paper, it would become two similar pieces. And we could choose where to fold the sheet, and by doing so we could differentiate the transformation. Through this simple process, we could create a standard of forms and we could take this process and create 3 dimensional process. But rather than folding this thing by hand, we could bring this in computers and coded them in algorithm. We can not only 44
fold them but also in other type of various alternation methods. In this sense, the systems we choose become the key of design. “The term ‘Parametricism’ implies that all elements of architecture are becoming parametrically malleable and thus adaptive to each other and to the context. Instead of aggregating a few platonic solids (cubes, cylinders etc.) into simple compositions - like all other architectural styles did for 5000 years – we are now working with inherently variable, adaptive forms that aggregate into continuously differentiated fields or systems. Multiple systems are correlated with each other and with the environment. All spaces should resonate with each other because within Postfordist network society all activities need to be networked and stay in continuous communication with each other.” (Patrik Schumacher, 2012) In traditional architecture practice, architects use their experience to design forms which control the power and order of space, the classical example is the Palladio’s Villa Capra (Palladio, 1552), the beauty of the building comes from Palladio’s experience of the ratio of shape and balance of the form. However parametric architects utilize digital simulation to find out forms, the essence of it is opened the gate for computers to adopt artificial logic of forms. In the work Kartal-Pendik planning (Zaha Hadid Architects, 2006), designer use surrounding
buildings as the existing context, use computer scripts to create a network that connects important factors in the shortest path. The quality of design turned to come from the quality of scripts designed by well understanding of elements behind the project and use proper rules to create forms. The parametric can not only mimic from nature, but also the totally new, artificial force field and human defined logics. Any parameters of the object such as geometry, position, color and transparency are related to the condition of generation process. Order is hidden behind forms. Our façade is designed for craft victoria headquarters. What we believed that we should present in our façade is the connection of the context of craft to parametric design. Craft is created by hand, the direct participation of artist, but the architectural tool we use is the parametric designing process which is using computer to creating form. The barrier seems distinct but actually shallow. As the craft is the accumulation of the force and fabric from artist’s hand we use the force of environment to making the same procedure. Our transformation base is from our test of the membrane and plaster. The pressure from outside pin and liquid plaster work together and created an intriguing continuous
surface. Through this alternation flat membrane become a parabolic surface. The wave crest and trough generate different characters from one average surface, some expose on exterior and some hidden in shadows. It gave us a basic idea of what can be happen in form when force is applied. “Force on the membrane” deducted an unimaginable effect of surface. It becomes the physical reaction system of our façade addressing public and privacy elements happening both in and out. The idea of craft is a seed. It drives the whole generation system but the process is not like drawing a portrait or carving a sculpture. It is like a procedure in nature, growing plant or developing embryo. The simple idea of craft will grow in parametric architectural language. The digital transition is natural.
tions. These characters are condensed in a code strip and help us to generate a most adaptive form of the building according to the system we developed.

The craft gesture appeared after the creation of script. Our input of the environment and function requirements for Craft Victoria become the pin in the our mold machine generating special surface of craft victoria. Suitability of the environment is the priori conditions of this process. Thus, the parametric exploring is not going away from the crafting context and environment but combine them with parametric technology into a higher level.
Rather than saying the form is control by computer operation, we believe that the form is generated by self-generation and evolution. We do not draw the shape exactly but set up rules to grow it by gradually input of information. The code is happening like the metal disk of the music box, it define where show rise and where should fall. The pin in this “metal disk” representing the force from outside world such as light condition, view from pedestrian and attraction to the next building and the force from interior, for example the requirement of large exhibition and the visual context of various func45

From the development of our touchstone, we decide to continue the with the similar making process for the cultural model. Ambitiously we try to make the whole facade in one piece in 1:25 scale. At the same time, this is the first time to use latex as our casting material because we love the physical behavior of it that it can create natural double curved surface and minimal surface. We are all very into the form shape by the mould. However, failure occur when we started to cast, the under extimation of the force by the plaster itself lead to this failure. All the plaster swell at the bottom due to latex’s properties and it was unable to fill up the whole mould.

… Parametric tools are algorithmically based, and therefore offer increased computational control over design geometry during design activity. Their adaptability and responsiveness to changing design criteria and requirements make parametric models especially useful for design exploration in complex and dynamic design settings… (ipek GÜRSEL DÍNO)
facade prototype In technical consideration we decide to make a 1:25 facade prototype continue developing our casting technique at the same time consider the prototype as a tool to test of the spatial and physical property of the facade. A more specific strategy to design the facade and construction method is also considered at this stage to make this project more comprehensive.

3.1 Cities without FACADE
by Atefehsadat Zohourian
ARCHITECTURE? Is it a social construction or it is facts determined by inexorable laws of physics, economics, buildability and climatology? The former have emerged from hypothesis which discussed architecture as a cultural fabrication and an embodiment of political concepts dissociated from natural laws, statics and climatic demands. The second one is about architecture which should be understood as much a physical construct as it is a social one. In this regard, we need to distinguish culture from technology which means, things would be differentiated from objects. Building envelope as the oldest and most primitive architectural element, demarcates inside and outside, natural and artificial. When it comes to faรงade, in addition to its crucial environmental and territorial roles, it operates as a representational device. In most buildings, even if physical security is the priority, the political performances of architecture is located in the plan or in the section, and this is just because of the understanding the envelope as a surface. Envelope, an incorporation of construction issues and representation converged in the design of physical limit of a building, involves the space crust- affected by the scale and dimension and also affected by its permeability to daylight- and respects to sun, wind and views. Moreover, the faรงade as the skin
of a building resists the pressure of the interior transforming its energy to something else; simultaneously it registers the violence of both spheres (inside and outside). Despite all these facts, there are new attitudes toward architecture which tend to spatial continuity cause architects to engage with borderless space, in other words space of flows; this attitude evolve outlooks of architects on faรงade. With respect to envelope technology, in this stage the different between the roof and the walls has disappeared and fenestration is no longer a crucial building problem. So it is important for architectural entities to develop various attachments to a multiple reality instead of remaining the inevitable products or representational ideologies Even if the walls and roof disappearing, reflection and silent analysis can affect our experience and sensibilities in the same way as before. The building envelope is still the primary regulator between public and private, inside and outside. To open ourselves to this perception and to perceive architecture spaces which form the frame of measure for lived time, we need to become the subject senses. The passage through time, light, shadow, color phenomena and material participate in the complete experience of architecture. This is the way that we realize the materiality of the details which form architecture.
On the other hand, in line with technology development, architects experience new approaches toward building design. For example, by virtue of the experimental continuum of enmeshed space, we perceive distinct objects as a whole. And as a matter of phenomenology, this is generative forces that are inducements to set architecture apart from natural science. Another criticism about contemporary architecture is that constructions often do not let us be in touch with the poetry and predictability of everyday changes, for instance we lost the haptic realm of architecture or even the perception of subtle mathematical properties. The reason, for that, is in bird’s eye view which is typically used by architects. Therefore, here is the reason that why it is proposed to construct urban spaces on perceptual principals, allowing for movement between the absolutes of architectural intention and the in definitive urban assemblage. Focusing on formation rather than form is another topic of concern. With respect to digital technology, there is a new outlook which is in contrast with the broadly aesthetic one that tends to impose form on building materials instead of letting forms emerge according to certain programmatic requirement. In this approach, architecture would be the result of computing forces.
But how might these operations be facilitated by the digital domain? Regarding the computer aided design, many architects used structure to operate parametrically as self-organizing systems which is not sufficient to fulfill the habitants need; in order to cover all the needs, it is necessary to have programs to make the whole design more logical. In this way, computers can be used as a generative instrument which is a part of the design process and architect as a controller would overseas the formation of architecture. The desire for timelessness which is caused by the cultural demand of stasis resulted in formal architecture. In order to advance this essence of discipline, an ethic of motion should imply to the form, so it would be shaped by the collaboration between envelope and the active context in which it is situated. In this way, topology allows for a multiplicity of vectors, and therefore, a multiplicity of times, in a single continuous surface. This is the key for building to persist for eternity. Because topological entities are based on vectors, they are capable of systematically incorporating time and motion into their shape as infection . The possibility of an animate field opens up a more intricate relationship of form and field than has been previously possible.
Rather than an entity being shaped only by its own internal definition, these topological surfaces are inflected by the field in which they are modeled. If an entity is moved in space, its shape might change based on the position within gradients pace even though the definition of the entity remains constant. To optimize the design process, mass production would be a good approach. But it is needed to advance the method to have customization. Customization will enable the automated production to differentiate each artifact from those that are fabricated before and after and will enhance the process to have the ability to differentiate to, distinguish architecture based upon site, use, and desire. Finally, with the hope of creating the utopia, it can be concluded that it would be more efficient to design a process of designing instead designing a building or even inventing production systems.

Enhanced mould test (sand) In terms of previous faliure in the cultural model, we make a few solution to restraint the swell of latex to achieve the surface we want at the same time maintain the smoothness of the object. There are three method we come up: the sand method, pin method and the waflle method. They all have different pros and cons, this test allow us to further develop our skill in casting and bring forward to the prototype model.

Despite of considering some features in mold design in order to create a smooth surface, the outcome did not fulfill the project expectation. So the need for developing the mold for components joints became more urgent. On the right: the final pieces for the facade prototype, which are around 10mm thick.

Construction sequence
As the same method for faรงade prototype, in the design of construction sequence, the whole faรงade panelized so it would be more economic and also easier to carry the precast components to the site. 88
Construction sequence
The precast panels are easy to tilt up and require less formwork in constructing the facade compare to insitu method. 89

Structure operates parametrically as self-organizing systems. In this regard it is used to shape the wall outline as a parametric constraints, therefore all the building would be whole itself.

To solve the structural problem, the horizontal surface of two floors has been pushed toward each other to create an arch. So in this way they bear the forces more efficiently.

As far as the aim of the faรงade prototype was to test the concept and the process in order to learn from the pros and cons, in this part the design will be analyzed to enhance the positive points and solved the setbacks. With the aim of parametric design it is necessary to develop the mold design so it would be possible to control the result in a more parametric way. Another step is to make the design more reasonable both in production and in assembly. Despite of dividing the mold into several pieces which has some advantages and disadvantageous, mold design need more alternation. For example, to rescue the faรงade appearance joints should be improved so the whole surface would be perceived as a whole continuous surface. Although there are some possibilities of producing the whole building on site in one unique component but it is not in line with the sustainable approach of the project. Pre-casting is one of the features of the project. To make this factor achievable, the design need to cut the components into pieces so it would be more comfortable to carry them to the site. With all due respect to this construction sequence, it is crucial to have the building envelope and its entities integrated. So the next step in this design is to create the parametric joints.

5.3 Grasshopper Definition
Definition Description: The component Divide Surface generates a grid of (u, v) points on a surface. How did we use it? We did use this definition in order to divide the strip so we can define the different parts on the surface of the strip.
106
Definition Description: The Image Sampler converts the color information of a generic image into numerical data. How did we use it? As far as our design based on forces so we assigned different colors to different functions according to the color science and their energy and used this definition to interpret colors to numbers which we can use as distance to move the points.
Definition Description: The Interpolate create a curve through a set of points How did we use it? To connect the moved points we used this component so we can loft them later. 107
appendix
Definition Description: The Pull component pulls a point to a variety of geometry. How did we use it? One of the basic of our design is attraction points. In this regard, we need to find the closest points to each attraction point and group them so we can move points according to how far they are from the attraction points.
Definition Description: The Vector 2pt creates a vector from two defined points How did we use them? Regarding to the opening direction, it was imperative to create the vector which direction would be defined by view through the building or either by light direction; so we used Vector 2pt component for each of the openings and used its direction to move the outer circle outline. After all the transformation, we entered a Minimal Surface component to create a natural loft between the transformed shape and the original one.
108
Group of components which generate magnetic fields according to point as poles and the power each has (for more information, please visit http://www. grasshopper3d.com and search for Rheotomic Surfaces). How did we use them? Referring the openings importance, we used this group of components to pattern the field lines on the faรงade surface which their junctions were used to position the little holes.
Definition Description: This component constructs a minimal surface based on boundary curves. How did we use it? Referring to our technique, it was necessary to find new components so we can simulate the outcome before testing it in reality. Therefore we used a plug-in which named Minimal Surface to shape the entrance and openings extrusions.
