Two day workshops  


Workshop "Parametric Live Control of a Milling Robot"  (details)
Workshop topic
This workshop will demonstrate the optimization of the robot milling data workflow from a digital design to a physical geometry. In Grasshopper toolpath calculations will be performed in real time providing instant design feedback.
The process of Flank Milling, which utilizes the full cutting length of the tool instead of just the tooltip, lends itself particularly well to the proposed workshop, as the geometric input – opposed to the usual rough and fine cut milling – consists of comparatively few control points of the tool paths. Therefore, these calculations can be done in real time, with the user seeing an immediate change to the object’s geometry and the resulting tool paths while performing changes to the underlying parametric model. Furthermore, the user can access each point individually and basically simulate the entire milling process within the CAD (Computer Aided Design) environment without relying on additional CAM (Computer Aided Manufacturing) or kinematic post processing tools (e.g. Kuka Camrob).
As a result of the parametric design process a robot control data file (G-Code) will be automatically generated. A Kuka KR60H Robot will be used for producing the developed flank milling designs.

What participants can expect to learn in this workshop
Participants will be introduced to the concepts of production immanent design, manufacturing parametric designs, writing G-Code for CNC machining and controlling a milling robot with existing parametric design software (Grasshopper).
Participants are strongly encouraged to produce their own individual “StackIt” designs within a 2- days ́ workshop: Using flank milling, a flat XPS-panel will be cut into stackable components resulting in a free form wall design.

Workshop "One DOF linkage manipulation using rigid origami"  (details)
Workshop topic
Flat plate linkages composed of quadrilateral panels are 1 degree-of-freedom linkages, and therefore offer interesting opportunities as their positions can be predicted by only one parameter. Curved folding of developable surfaces can be rationalized as such linkages, by creating quads from linking the ends of ruling pairs.
The workshop aims to show participants how to create varied forms of rigid origami and curved folding computationally in Grasshopper, Freeform Origami, and Rigid Origami Simulator and then to realize them with sheet materials with the use of CNC machines and hand folding.
The goal of the workshop will be to realize folded forms as articulated geometries whose states in various points in the cycle of folding can be defined and controlled. This will allow for prediction of - and reverse engineering from - given positions of parts of the linkage; analogous to a robotic arms and hands.
By realizing the geometry in both physical and computational environments, an iterative approach is taken to the development process, as participants translate code into craft – and back.

What participants can expect to learn in this workshop
The participants can learn the basic kinetic geometry that arises in creased developed surfaces, design methods to apply such shapes and mechanism through the iterative use of computational tools and real materials.

Curved folding is a developable surface that is composed of both creased and smooth curved developable surfaces. Such a surface can be modeled as a rigid quad-mesh origami, which is known to have one-DOF kinetic motion.

This workshop explores the design of forms of such kinetic forms through the participants' iterative interaction with software and real materials. Through this workshop, the participants can understand the basic geometric behavior of curved folding and the ways for designing and fabricating its pattern to suit the specific requirements of this workshop, i.e. articulation.

Workshop "Info-Informalism"  (details)
Workshop topic
Live, data-driven associative modelling (generative design, integration of geometric and non geometric design properties)
This workshop seeks to address the current state of associative design and manufacturing. While the tools we adopt for the design of the built environment are increasingly allowing us to operate on larger and larger scales, they remain disconnected from real time data sources. This workshop proposes workflows and techniques which allow designers a connection to real world, real time data. Humanity’s largest creation is the city, a constantly morphing organism with an amazing capacity to compute informal organizations. It is our aim to view the city as a computational system, capable of calculating with a capacity which far exceeds that of our current supercomputers.

What participants can expect to learn in this workshop
The workshop will implement several prefabricated sensory nodes which participants can easily connect to, manipulate, and share. The idea is to generate a broadcast system where all of the participants can subscribe to a sensory feed which will be driving certain parameters in an associative model. The sensory nodes will be prefabricated in the Fab Lab BCN and brought to Zurich in order to be able to begin receiving and relaying data on day one. Workshop participants will be working with Grasshopper, a generative, nodal based design environment where users will be able to receive real time sensor data in order to interactively update their models. Connection to the sensory data will be done through gHowl, a set of custom components written for Grasshopper which allow users to connect to existing data streams, and also to emit manipulated data back to the sensor data stream.

Workshop "Building our design tools with Grasshopper and Rhino Common"  (details)
Workshop topic
Often we as designers face challenges with geometry we know how to construct and handle, but would like to automate and use in more efficient ways. Other times, we would like to consider many results based on a set of principles that are well known and established, yet tedious to implement. In both cases, a structured and simple geometric framework can help building the right set of tools and putting them into practice. Often, the fundamentals of how to use such a framework can appear to be daunting. This should not be the case given that the designer can have a good introductory training.

What participants can expect to learn in this workshop
To use the mathematical and geometric entities in the RhinoCommon (http://wiki.mcneel.com/developer/rhinocommon) library to successfully implement simple tools, such as point, line, simple surfacing and meshing utilities that might be needed in everyday’s tasks. The most interesting part is that, given time, these fundamentals can then be extrapolated by the designer to help him accomplish more and more simply.

Workshop timeline
This is a 2-day course
.

1st day: morning
Introduction into the principle of Network Dynamics and what it means for structuring a design team. Theoretical explanation of its strength and examples of proven principles. Followed by the practical introduction to the workshop intself; the structure, the role playing and team approach, the goals and results. Finally an introduction to applicable resources: Architectural modeling (Rhino), Performative Analysis (ECOTECT), Structural Analysis (RSTAB). The goal is not to increase the software skills, but rather the impact analysis has on architectural geometry. The analysis software will be intensely guided by the workshop tutors.

1st day: afternoon
Creating (continuing with a basic) an adaptable model in Grasshopper: Applying parametric modelling techniques. The workshop will emphasize on a bottom-up approach, in the sense that the determined relations and parameters lead to a generic component design. Building a non-standard architectural design inhibiting the awareness of feasibility constraints. This means that a double curved facade needs to be faceted; the size of each facet should not exceed the dimension limits of a glass plate, etc. This common knowledge will be implemented by the experienced workshop tutors. The resulting parametric model is the blue-print of the architectural geometric 3-D model before applying Gravity, Climate and Contextual force fields (day 2).

2nd day:
The student design team consists of the Geometry-agent, the Climate-agent, the Construction-agent
and the Urban-agent. Assisted in software handling (ECOTECT, RSTAB) by the workshop coordinators, each design team will optimise it's 3D geometric model. This performative iteration will create substantial awareness and insight for design consequences. The team based approach makes the agents (students) aware of the added value of operating collectively. The goal is to understand that the sum will be more than the addition of its parts; collective intelligence in design teams.

Workshop "Generative Performative Modeling via Grasshopper & Ecotect through Geco"  (details)
Workshop topic
“Designing, modeling and evaluating" freeform geometries as architectural elements which are highly differentiated and correlated in their systems and subsystems is a task which is not possible with traditional methods. This is the time of algorithms and scripts for pushing the limits and helping designers pass the limitation of current 3d software.

Thinking about complex geometries, we need appropriate tools, especially software tools, which are capable of creating and controlling these geometries, their properties and simulating different variations.

Ecotect is a highly visual software for architects to work with environmental performance issues. It is designed for early stages of conceptual design, and encourages play to understand environmental factors and interactions.

Grasshopper as a parametric modeling plug-in for Rhino, is a graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools, allows the user to construct their own “explicit history tree”. With little programming experience, users of Grasshopper can define relations and correlations to generate parametrical architectural models.

By exploring Grasshopper in this workshop, the participants should conceive how to design geometries through algorithmic process as prescriptions of computational processes. In addition, the workshop will present how to integrate a criterion of design guided by evaluating performances of generating geometrics of architectural forms; the participants will construct a relation between building performance and building geometry.

Evaluating (Solar Radiation-Daylight Performance) performance will be simulated by sustainable design analysis software Autodesk Ecotect. Data feeding from Grasshopper to Ecotect is based on an interface developed by [uto] which offers a direct link between Rhino/Grasshopper. This plug-in has the automation spirit of transforming performances data which consequently enables to combine a generative and performative modeling into one criterion. So the workshop will combine geometrical subjects with algorithms and will address some Performative design issues in architecture in an ‘Algorithmic’ method.

By creating an evolving algorithm which encodes a generative algorithm with a performance feedback loop, the computer will be used to generate and evaluate possible configurations, and explore
optimal and approximated solutions for the supposed problems.

What participants can expect to learn in this workshop
- Conceiving the relation between building performance and building geometry.
- This workshop will have the focus on the integration of current energy design and engineering tools within the design process. For that, we will use Autodesk Ecotect Analysis and McNeel's Grasshopper to develop environmental design solutions to respond to external influences. This should give participants a functional understanding to improve performance and the design of a building in the context of its environment.
- Creating generative performative forms and surfaces based on Evaluation performances for e.g. Solar Radiation, Daylight Performance by Ecotect with Grasshopper through the usage of Geco.
