Event 10.10.21: ACADIA

GLeMaire — Thu, 21 Oct 2010 17:27:15 +0000

Friday October 22^nd beginning at 6:30pm Pratt Institute School of Architecture will host the The Association for Computer Aided Design in Architecture (ACADIA) presentation and a roundtable discussion concerning adaptation and selection in architectural design. The event is entitled EVOLUTIVE MEANS and includes several designers and academics from around the world. This event is in conjunction with an exhibition in the Hazel and Robert Siegel Gallery as well as with The Cooper Union School of Architecture and should prove to be an exciting event.

ACADIA was formed in the early 1980’s for the purpose of facilitating communication and critical thinking regarding the use of computers in architecture, planning and building science. A particular focus is education and the software, hardware and pedagogy involved in education. The organization is also committed to the research and development of computer aides that enhance design creativity, rather than simply production, and that aim at contributing to the construction of humane physical environments.

fundamentals of surface modeling

RSarrach — Mon, 21 Sep 2009 04:24:47 +0000

We will be placing tutorials & base files for all 7 forms in the “periodic table of form“ (located above) up on df. The text below is an excerpt from the core 77 article entitled “A Periodic Table of Form: the secret language of surface and meaning in product design”, by Gray Holland. It serves as a wonderful conceptual bootstrapping mechanism for our Rhino Boot-Camp Workshop 001.

“If there is an empirical meaning behind form then, how does it manifest across the natural and into the man-made world? Going further with this notion, let’s deconstruct the meaning of form naturally, and then distill that meaning into some simplified geometric categories technically. In order to define these categories, I will ironically employ a three-level definition of surface continuity from the engineering CAD lexicon: Positional, Tangential, and Curvature continuities.

It’s useful to think of these three types as steps in a ladder, with each building on the definition of the last. Positional continuity [C⁰ or G⁰] refers to the hard edge created when 2 surfaces intersect. Tangential continuity [C¹ or G¹] is the next level, defined by a circular arc creating a relatively smooth transition between these surfaces. The quality of this transition is best visualized by a straight line drawn between two circles: the line’s only point of contact with each circle is tangential. This level of continuity is often described as a basic fillet in most solid modeling systems. Although smooth, there is a characteristic “break line” of tangency denoting where the circle meets the line.

Curvature continuity [C² or G²] is a bit trickier to describe. Technically, it occurs when the rate of curvature between 2 continuous surfaces are the same. Visually, it is when one cannot tell when one surface ends and another begins. In the CAD world this is often referred to as class A surfacing, and is the domain of surface-based modeling software like Alias, Rhino, and Catia. The primary benefit of Curvature’s quality is the ability to control smooth reflections across multiple surfaces, generating the elegant sculptural results necessary in the automotive industry. The technical renderings below illustrate these visual qualities better than any verbal description could. Please pay attention to the subtle differences, particularly the Tangential line marking the fillet’s point of contact with its adjacent surface, and how the reflections break there as well.”

RoboFold + formative technologies

RSarrach — Fri, 21 Aug 2009 21:08:09 +0000

This is an image of a formative technology coming out of RoboFold. It is a new formative computer aided manufacturing technology currently under development and could be promising considering that when a human hand enters into the production process it = $$$$$.

RoboFold is currently developing manufacturing processes utilizing industrial robots to directly create sheet metal forms. The system requires no tooling thus enabling the creation of new forms unavailable with current methods.

Please follow below for more info and videos–>>

The patent pending technology utilizes standard industrial robots to directly manipulate sheet material into complex surfaces by folding along curved lines. The RoboFold system will be controlled by a simple software plug-in to enable design, engineering and production planning in a familiar CAD environment.
