Digital Design Technology 2

Architecture, Digital Production
2020S, scientific seminar (SEW), 3.0 ECTS, 2.0 semester hours, course number S03258


Digitally printed matter is often lacking the irregular, vivid and tactile qualities of analog drawings that are results of a plethora of parameters of the physical world and its materialities (i.a. bleeding or drying of the inkpen, smudges, scratches, humidity changes, ...)
This course intends to give students the possibility to explore the vast potential for unique and individual expression, which is very constrained in modern processes (that allow for unlimited and exact copies).

The pen has always been an essential tool in the communication of architecture but has lost importance in the realm of digitalization. As a consequence the analog production of drawings has also lost significance and especially presentation drawings are nowadays primarily digital renderings, which get printed fast and efficiently with laser or inkjet printers. Although the digitalization has undenyingly brought a lot of positive advantages to the architectural production, the loss of the analog drawing also left behind these gaps that could not or only partly be filled by digital media.

This undertaking is an attempt to use the analog drawing as a platform for experimentation and to interweave the best of the digital and analog worlds.

Over the course of the semester students will get a brief overview of the history of computer arts and computational drawing from its beginnings in the 1960s to contemporary works with an emphasis on algorithmic programming and its physical manifestation through CNC (drawing) machinery (due to the COVID-19 meassures, the latter will be alternatively communicated as good as possible through (moving) imagery from the worldwideweb and collected/linked on a central webpage)

Examination Modalities

During weekly sessions we will develop several small Grasshopper definitions based on artworks of the past. In between the sessions students are asked to bring these into the physical world.  (due to the COVID-19 meassures, the latter is not possible and the students will have the possibility (free choice, not necessary for passing) to make up for it in a reduced manner after the lockdown in a type of workshop. To compensate for the missing physical work with the machinery, we will focus on the programming and turn to more architectural applications of it, based on students' suggestions and interests)
The course is under continuous assessment (at least 70% presence at tutorial sessions is required to pass).
Additonally to the weekly experimentations, each student will produce one final pen-drawing/artwork to be presented during a Vernissage in the "Square" at the end of the semester. (due to the COVID-19 meassures, the latter is not possible and the students will have the possibility (free choice, not necessary for passing) to do so after the lockdown, to have the chance to exhibit their work and get a broader range of feedback)


This course is specifically adressed to students with a background in Architecture and will focus on object oriented programming (Grasshopper/Python -> no pre-knowledge required) and intends to hack/make use of the available machinery of the DDPLab. ((due to the COVID-19 meassures, only on a hypothetical level)
Students should be proficient in the 3D-modeling Software Rhinoceros and be able to work independently on a high level between the sessions.
Curiosity is mandatory.

max. 15 participants  (individual work is encouraged, but teamwork is possible if preferred, priority is given to students of architecture, who did not yet participate in the course. )

Tutorial sessions will be held via zoom at the same scheduled dates and will be available as recorded video in the course folder in the OwnCloud.

Participants are kindly asked to bring their own Laptops and Software.
