Parametric Product Design

Parametric design workshop for industrial designers at Staatliche Hochschule für Gestaltung (HfG) Karlsruhe on the invitation of Prof. Volker Albus & Stefan Legner. The workshop focussed on concepts of parametric design to generate parametric geometries creating definitions and scripts (Grasshopper for Rhino3D).
Full workshop description avaiable in German only: 
Workshop: Einführung in parametrisches Entwerfen – HfG Karlsruhe
Der auf 4 Tage angelegte Workshop „Einführung in parametrisches Entwerfen“ erarbeitet Grundlagen des Regel-basierten Entwerfens anhand von einfachen Skripten und Definitionen. Als der Logik des Regel-basierten Entwerfens lassen sich durch Veränderung der Parameter eine große Anzahl an Formen und Strukturen erzeugen und kontrollieren. Der Entwurf verlagert sich durch das Aufstellen von Regeln und deren mathematisch-geometrischer Ausführung zu einem Prozess des Entwerfens „vor der Form“. Das aufgestellte Regelwerk enthält sämtliche Möglichkeiten zur formalen Entfaltung, welche vom Computer zu bestimmten Parametern ausgerechnet werden.
Der Workshop beginnt mit einer Einführung in Rhino3D und deren Programmiersprache Rhinoscript. Im weiteren wird die graphische Programmier- Software Grasshopper erklärt. Mit Rhinoscript und Grasshopper lassen sich innerhalb von Rhino3D digitale Systeme wie Loops, Funktionen, Rekursion, Oberflächen-Parametrisierung und Fraktale erzeugen. Dadurch am Computer erzeugte Geometrien können an verschiedenen digitalen Maschinen getestet und fabriziert werden. Die materiellen und maschinen-bedingten Rahmenbedingung schränke die Auswahl ein und führen zu einem iterativen Näherungsprozess von Entwurf und Maschine.

Digital Design & Representation

Digital Design and Representation stand at the core of the education of architects and urban designers. Due to the proliferation of computers, the increasing computer literacy amongst incoming students and the fundamental shift in the profession towards the digital, digital design and representation needs to be re-assessed all together.

DMY 2010 Berlin

The 'Evolving Monument' is proposal to catalogue the objects developed during the Open Design Laboratory. As a process, this display system will grow, change, disrupt and/or project the input of all participants during this 5-day event. This public effort aims to form the workshop’s institutional memory while serving as a generative exercise in digital fabrication for public learning and collaboration. Initiated and moderated by Luis Berríos-Negrón and Aurel von Richthofen

Beyond Rendering, TU Berlin

Aurel speaks on the topic of architectural representation on the conference Beyond Rendering organized by Daniel Lordick at TU Berlin. Architectural representation had only recently moved towards image driven representation forms. The "parametric shift" indicates a tendency towards the text, more explicitly the script.

Islamic Patterns

Islamic Patterns / CAD 1 @ GUtech 2010 - present The 1st CAD seminar introduces students to fundamental concepts of geometry and scale. Students start with analysing Islamic patterns. These traditional patterns are based on circles, squares and hexagons and can be found in many islamic ornaments throughout Oman. They entail basic vectorial transformations, such as translation, rotation, reflection and scale. While re-drawing the patterns in CAD, the students start to re-interpret the pattern in their drawing. Students resolve linear intersections and treat the drawing like an architectural drawing. Later the 2D CAD drawing is interpreted in 3D using extrusion and rotation. This process requires the addition of information. Students are then asked to re-introduce a scale and to read their shapes against a possible programs.

Parametric Urbanism

CAD 4 @ GUtech 2010 - present In their last regular CAD semester students are introduced to parametric modeling. They elaborate protocols and definitions that can handle design relevant parameters and yield 3D geometries. Student evaluate the resulting shapes and re-interpreted them as architectural or urban forms. A special focus is laid upon the production of variations and repetitions. Once students master parametric design from scratch they use building information modeling software. Again, they work and update a digital model that can be enriched with information to produce technical drawing set, a rendering or a fabrication file.
