Digital Crafting Events: Workshops

Workshops precede the seminar giving hands-on practical knowledge and access to the toolsets involved in the topic. These tools are both digital and crafts oriented. The workshop are structured around the invitation of a guest researcher that introduces a given technique and technology to the network allowing the network participants immersion in a given set of research questions, techniques, computational problems and tools.

Workshop 1 – Parametric Design / Encoded Behaviour
Workshop 2 – Wood construction
Workshop 3 – Concrete and CNC
Workshop 4 – Generative Logics
Workshop 5 – Textile logic

Digital Crafting Events: Seminars

Seminar sits at the end of workshops and allow a theoretical framing of the event. The seminar holds talks by the guest researcher, the network participants and other interested parties. The seminar includes presentations of the partners’ and guest researcher’s existing research inquiries, active participation with assignments given up for discussion in focus groups and ends with a reflective discussion in respect to the overall aims and objectives of the Digital Crafting bid.

Seminar and strategy meeting “Parametric Design in Practice”

16 November 2009, The Royal Academy of Fine Arts, School of Architecture, The Red House

A strategy meeting was held in November to discuss the Parametric Design workshop in early 2010 and plan other upcoming workshops and seminars including the first symposium to be held in May.   The full-day meeting had presentations by designers from various fields and institutions who are using digital design and fabrication.  Following the presentations, there was a discussion of key themes raised in these projects which can be explored in the Digital Crafting Network.

Architect and engineer Hauke Jungjohann from Knippers Helbig Engineers and formerly with Herzog and de Meuron presented “Parameters to Design/Design for Parameters”, a lecture which featured projects he has worked on including the Museum of Tolerance by Frank Gehry, the Milan Fair Project by Massimiliano Fuksas, and the Roche Tower by Herzog and de Meuron.  Discussion about the themes in the lecture included questions of how to model material performance and the question of whether a project should have one parametric model or many different ones.  In the case of many of the projects that Jungjohann described, the architects brought a nearly fully formed shape that needed to be rationalized, defined and built.  This raised the question of how architects could use digital tools for formfinding and at what stage parametric design should enter the design process.

Martin Tamke from Centre for Information Technology and Architecture (CITA) gave a lecture titled “Parametric Formations” and introduced ideas of formfinding as a way to create form as a dialogue between material and gravity.  He discussed how parameters can be linked to analysis and illustrated these ideas with examples from CITA´s recent projects.  From these examples, discussions emerged about mass customization becoming more practical due to industrialization of the building process and the idea that early planning can reduce costs and time associated with using digital fabrication for unique components.

Jan Karlshøj from Danish Technical University presented a lecture about using cost and time as parameters (the 4th and 5th dimensions) of digital modeling.  Karlshøj discussed the possibility of using multiple interacting tools, and asks “should the model be where all the information is held?”  This led to discussions of how production information can be added as a layer of information in a digital model and how changes can be incorporated into a complex model.    How can designers manage the intersections between digital tools and information?

Asbjørn Søndergaard, from Aarhus School of Architecture presented his current research into optimization in architectural design, focusing on parameter design as a key design challenge.  What should the role and influence of architects be in the optimization process and how accurate are the results of optimization?   Søndergaard presented his ideas about creating digital tools that use flexibility and allow for multiple options, with ideas of modeling the relations between elements rather than just the individual elements.

After the lectures and discussions, possible content and guests were discussed for upcoming workshops and seminars.  Each member of the Network is considering: What is parametric design in each of our particular research contexts? What are the key research questions for the Network?

Workshop/Seminar 1 “Parametric Design - Encoded Behaviour” - A report by Terri Peters

Digital Crafting Feb 8-10 2010

The first digital crafting workshop event “Parametric Design – Encoded Behaviour” was held at the Royal Academy of Fine Arts, School of Architecture in Copenhagen February 8-10 2010.  Organized by Martin Tamke of CITA and London-based Paul Nicholas of Mesne, the three-day workshop brought together seventeen designers from the fields of textile design, engineering, architecture and computation to explore ways of understanding material performance and behaviour.

The aim of the workshop was to create a research environment to observe, measure and then input and relate material behaviour to a digital parametric model.  This was seen as a way to begin to understand and control material performance in a component system.   The workshop included short group design exercises, material experiments using timber and textiles, grasshopper tutorials, guest lectures by Paul Nicholas, Mette Ramsgard Thomsen and Hauke Jungjohann, group discussions and reflections on the design and production process, and group component assembly of a working 1:1 prototype or “demonstrator”.

How can we understand the relationship between geometry and material property?

In the workshop we focused on a simple parameter, the bending of a linear material, because this allowed us to simulate the behaviour of the wood and encode this information into the digital model.  We used Grasshopper as a digital tool, as a visual form of coding, as a platform to begin to understand coding.   The relationship between the material and the digital was approached at full scale, a 1:1 material study, through encoding the information gathered through experimentation in the digital model.  During the process, we discussed issues of accuracy, because by measuring by hand there is a degree of abstraction and error, and together we questioned if digital design should be focused on accuracy or relationships between elements. In our group discussion we questioned “is there something that we learned from actually observing and bending the material that we could not have learned otherwise?”

Are we bending sticks or are we discussing parametrics?

Using this technique of directly, empirically testing materials, we developed new ways of thinking about something complex (the bending of the sticks is a sine curve, and there are mathematical equations relating to the constant length of the material and how it compresses) without needing to understand the mathematical formula behind it.  In this way for designers, material behaviour can become a design parameter. Parametric thinking offers the opportunity to link between material behaviour and computation – we began to ask ourselves, “how can we design the relationship between physical properties not just information in parametric models?”   How could this new parametric way of thinking change the way architecture is designed and made?

How can we consider assembly and issues of fabrication?

In conventional design practice, often due to cost and time constraints, thinking about materiality usually comes at the middle to end of a design process.  In contrast, during the workshop, material quality and performance were seen as design driver, at the initial stages of the design.  We discussed what happens after design: fabrication and assembly.  Even with digital design and mass customization, the assembly of components can be time consuming and a design task in its own right.  We discussed architectural examples of Sydney Opera House, and the Seattle Library where the contractor was tasked with treating the assembly of the building components as a design exercise.   In our group discussions, we talked about how designers can reduce and simplify a design problem to the minimum number of parameters rather than slavishly trying to describe reality.  Too many parameters can lead to unpredictable complexity, potentially making the digital model unusable.

Lectures framing further discussions

Three lectures on the final afternoon illustrated design and textile works using a digital approach with material sensibilities but at vastly different scales. These lectures were used to frame discussions about the implications and applications of “encoded behaviour”.

Hauke Jungjohann from Knippers Helbig Engineers showed the Shenzhen Airport project that he worked on at  Massimiliano Fuksas´s office, which has a 1.3km long concourse and a double skin façade that used parametric panelization tools to control light, drainage and appearance. Jungjohann illustrated how in this project it was key to develop tools to design basic element variation to create something that can adapt to double curved surfaces.  Drawing on ideas from the lecture, we discussed ideas about how a parametric model can simulate material behaviour during the design process and how computational tools could allow more customized and useful designs.

Mette Ramsgard Thomsen from the Centre for IT and Architecture (CITA) showed a new project called “Listener” which showed how these ideas relate at a personal, human scale and can incorporate ideas of responsiveness and adaptation.  The project illustrates ideas about computational tools, and what happens when designers are able to design materials.    We discussed the way that these ideas could lead to lighter and more intelligent building practices.  We also discussed the limits of digital tools, and what happens when the hardware or software being used becomes outdated?  How robust and secure are digital models or information?

Paul Nicholas´s lecture illustrated the importance of communication in design projects using several examples of geometric layering including a project which was a series of 10m tall steel sculptures in Melbourne.  The design was described and communicated to all collaborators using a single digital model.  Building on these ideas and projects, we discussed how moving information from upstream in the design process down to the beginning stages.   How can design information be communicated during the design process? When should a digital model be introduced in the design process?

Evaluation: Workshop/Seminar 1 “Parametric Design - Encoded Behaviour”

During the last day of the Seminar Workshop we had a joint evaluation session. The aim for the evaluation was to learn the lessons of the first workshop so as to improve the next 4 workshops. The evaluation focussed on a series of key question:

-           How was the running of the workshop?

-           How was the preparation of the workshop? (asked to Paul Nicolas and Martin Tamke)

We divided the 16 workshop participants up into groups that reflected on each of these questions. After a 40 min session the group reflections were presented and discussed in forum. Each group was asked to separate positive and negative feedback so as to give a clear indication of how we can improve the sessions.

The evaluation was very fruitful. It gave a good picture of what had been successful and what was needed to be amended for the upcoming research workshop/seminars.

These are the results of the evaluation.

Running the workshop


Subject and tool

The subject was seen as well chosen and relevant for the entirety of the network. Understood as a way of creating a basis for discussion for the rest of the workshops the subject: Parametric Design and the focus on material fabrication allowed the group to create a shared framework for discussion.

The subject was also seen as tying in well with the first seminar run in December 2009.

Schedule and material

The tight schedule and extensively prepared material was seen as a key part establishing the success of the workshop. Martin and Paul’s work was tightly packed and the programme was well described giving us all a good overview of the two day workshop. Their material allowed concepts and technologies to be discussed and learnt but also included “prepared leaps” by which the group could fast forward through the process of parametric design.

Lectures and presentations during the workshop

The workshop was intersected by a series of presentations by workshop leaders guest Paul Nicolas and network participant Martin Tamke. These were seen as strong presentations allowing the group to understand the wider framework of the research question addressed by the workshop.

The exercises

The first exercise was seen as particularly positive. This exercise “nailed the theme” allowing every one a direct understanding of what was at stake within the given research question.

The practical experiments were seen as positive. Working directly with material as well as software allowed a hand-on engagement with the technologies at stake. The practical experiments were seen as ways of creating “a common platform”, “an anchor point” and “setting the scope” for the workshop.

Group structure

The workshop was structured so that all work sessions happened in groups. The groups remained the same during the whole workshop allowing a shared language to emerge as well as letting members evolve their conversations and research sharing. The groups were seen as a good foundation for the workshop. It was seen as positive that the groups mixed the different institutions letting people from engineering; architecture and design work together and exchange concepts and material practices.

Amount of participants

In all we were 16 participants in the workshop. This is seen as a good number allowing for real collaboration and exchange while still maintaining diversity and “groups within groups”.

Workshop holders

The workshop holders were given very positive feedback in the way the workshop was run and their presence. It was seen as positive to have a workshop guest coming from outside the network to introduce new concepts and technologies.

The network participants

The network is a very dynamic structure. Participation has been dynamic meaning that different people have entered the network since its first up start. This is seen as positive dynamism. The network also supports the research students from the involved institutions. As many of the environments have emergent research environments we have also supported some involvement of masters students from DTU and Kolding Design School. Again this has been seen as positive supporting diversity in the expertise of the network participants. The network also has a strong international participation with both foreign researcher and research students working in Denmark as well as international participants. This is probably occurring because of the English language that the international collaborations ensure and is again seen as positive supporting diversity of experience and broadening discussion.

The seminar presentations and discussion

The workshop is succeeded by a seminar session. In the Parametric Design workshop/seminar presentations were done by Paul Nicolas, Hauke Jungjohan from Knippers Helbig Engineering Office in Stuttgart and Mette Ramsgard Thomsen, CITA. The presentations were highly varied showing work from practice and research and of extreme different scales and design traditions. Bringing together the mega scales of airport design in Shenzhen and the micro scaled of parametrically steered textile designs the seminar allowed a discussion across disciplines, scales and materials.

This breadth was seen as positive for the network allowing very different experiences to be discussed within a shared framework of technological understanding. It allowed ideas to “zoom out to the big scales of production” and understand how the discussed technologies have consequence on architecture design culture when implemented.


The exercises

Because the first exercise was seen as excellent many of the participants wanted to have been given the chance to continue working with this experiment. The first exercise gave the groups the opportunity to work directly with the material developing their own structures. Many wanted to have continued to do so.

The reason this was not planned was so as to make sure to take the groups through the entirety of the process. The balance between the individual experiment and the process was therefore discussed as a key consideration in the planning of further research workshops.

The demonstrator

Developing the demonstrator was seen as negative. The workshop was structure in a way that would allow the groups to build a shared final element at the end of the two days. The production was how ever badly organised and the final product was marred by over production of some elements, bad detailing and poor execution.

It was therefore discussed whether we need to focus on the production of a demonstrator and whether it is feasible to develop something of quality in such short time frames.

The lessons learnt were that the materials must be fully tested before hand. We had bought materials for the workshop and some had arrived a bit thicker than anticipated. This proved a big difficulty.


The network expressed the need to document the work along the workshop so as to allow for reflection and developing shared understanding.

The documentation could be in form of accumulating power point presentations shared in structured sessions through out the workshop. The workshop ended in a final review of the material given which led to the choosing of the demonstrator to be developed. However, this sense of conclusion could be more articulate and present in the process.

To do so it is important to make time for this.

The tools and technology

The group found that it would be good to send our the programme of the workshop a bit before hand as well as the introduction to the tools that will be addressed giving participants the possibility to prepare and learn the tools in advance.

Expectations and outcomes

Some participants were unsure what was expected of the participants. We need to develop a clearer image of what the participants’ role is during the workshop. Even if the key anticipation is sharing and exchange then we need to be explicit about this intension.

In the same vain as in the negative feedback about the demonstrator it is important that the anticipation for the outcome of the workshop is better declared. What do we think a result is for the workshop? How do we know it is a success?

Preparation of the workshop


Being prepared

The key positive feedback in the preparation of the workshop was that Martin and Paul had had the chance to do the workshop before with students at KARCH. This allowed them in depth understanding to eh process and the question as well as the means by which these tools and technologies can be introduced.

This was a unique situation happening because of the cancellation by the intended guest Marc Fornes. We therefore realise that we will not be able to run the workshop with as much insight into the process in the future. We therefore need other ways of preparing the workshop and leaning on the expertise of the workshop holders.

Time scheduling

The time scheduling was seen as key to the success of the workshop.

Materials and technologies

The workshop holders were very positive about the mix between digital and physical tools. They said that this duality creates particular means by which the questions can be understood.

Preparing hand outs and tutorials

The workshop holders had prepared extensive hand outs by which the tutorials for the exercises could be explained. This was seen as a slight waste of time as they were hardly referenced and teaching was done in person instead.

Group design periods

The group design periods were seen as particularly successful.


Material surprise

The sourcing of the material was harder than anticipated and led to the buying of material that was slightly too thick. This led to the failure of the demonstrator. It is therefore recommended that all materials as extensively tested and sourced in as good time as possible.


The workshop holders found that the software presentations were perhaps a bit too detailed and that the groups did not actually have a chance to learn all of the material prepared.


The workshop holder found that we need better instructions in the production of the final demonstrator.

Preparation time

The preparation time is about 5:1 meaning that even counting the fact that the workshop had been run before with students they needed 10 days to prepare a 2 day workshop. This is an important part to take into account.

Suggestions for future activities

The evaluation leads to a series of suggestions:

Developing a pamphlet

The group was interested in the idea of “what the guest brings home”. It was suggested that the network would make a pamphlet with the work of the members to give to the guests to bring back with them.

What is the output?

The output should be the development of new research questions emerging from the varied experiences and expertises of the research network

The exercise

Could the exercises be structured around multiple “products” rather than one overriding demonstrator? Could the focus be on tests rather than the demonstrator?

Modes of reflecting

The workshop-seminar constellation is a means of reflecting. Could there be other ways of extending the models of reflection in the network:

-           Could we have mixed modes of hands-on and analytic reflection?

-           Could we address different scales of technological implementation?

-           How can the blog become part of the reflection?

Digital Crafting Events

The network activities are structured around core 5 workshop/seminar events and two symposia.

The workshop/seminars are aimed strictly at the network focusing on specific theoretical, technical and practical research questions and potentials defined by the network. The workshop/seminars are sites for gaining as well as critically reflecting on experience and know-how in the field of Digital Crafting.

This build up is consolidated in two open symposia inviting international researchers representing state of the art research and findings to further frame and perspectivise the themes of the workshop/seminars and is aimed at the network but will open to a wider group of researchers, architects and students.

The seminar and workshops are coupled investigations into the given topic They are thematically organised and each focuses on a general theme introducing specific questions of formal, material and structural organisation and relating digital as well as analogue techniques. This allows for the participants of the network to contribute different research interests and technical and theoretical skills and fields of expertise. These questions are focused through the invitation of guest researchers organising hands on workshops and/or theoretical framings.

Digital Crafting Events: Symposia

The two symposia will develop the theoretical framing of the project. The aim for the symposia is to critically reflect on the scope of the research project, the international context and its practical and theoretical consequences. The symposia will invite international researchers and practitioners to present a critical reflection of the field.

The two symposia will focus on the dual nature of the inquiry. With a central interest in the relationship between the encoded and the material the symposia will seek to develop the intersections between these two strands of thinking.
