## waffle

Here are two macros that automate some of the classical structural styles in today’s architectural geometry. They could be developed more to include joint details however. It is a relaxing experience to study macros, when the process doesn’t have an algorithmic expresssions (such as recursion, iteration or conditionals). It is today’s subject in first year design computing course at İBU. The first one requires at least two curves already present in order to define a lofted surface (to be “waffled”): ! ; Waffle Structure Macro 2 _-loft _pause _enter _sellast _setobjectname […]

Following posts will include some of the final projects, completed in Basic Design Studio, İstanbul Bilgi University Faculty of Architecture in 2013. Below, you see an amazing work of group 1, an interlocking system that presents diversity and structural integrity at the same time. This project initiated a hard discussion among final jury. I think the interesting geometric underlying, great precision for a hand-made computer modeling of each piece, and the layer of structural details that generates a pattern itself, make this work an outstanding example of our intentions in […]

RhinoNest is a plug-in for Rhino and a set of components for Grasshopper. I tested it using my old interlocking fabrication definition (here) and (here). I downloaded RhinoNest from this website and installed. However I sounded a little complicated at first sight. Then I found a sample definition (here) and modified it a little bit to meet my purposes. First of all, I added orientation components (grey group below) to align all sections to WorldXY plane. Then RhinoNest is integrated to the definition. After you set input parameters, just double click on the […]

A previous work showed a method to create interlocking sturctures to be created without boolean operations. This time, a small addition is made to create waffle objects using two surfaces, one is the top surface, the other is bottom. It was a small modification at the beginning; to replace “extrude” component with a “edge surface” component. But the interlocking details are now different on each intersection, so another modification is made at drawing of the rectangles. This definition can be downloaded from here [GHX: 2012_01_29_contour2] along with a test surface […]

It has been a tough problem for me, for last two days. Parametric model of an interlocking structure (sometimes also called egg-crate, waffle or contouring structure) can be created easily in Grasshopper using Contour component a couple of list management operations, and a boolean (or region) difference event. However Rhino and Grasshopper are very slow at calculating boolean differences on both solids and surfaces. Fabrication models of such structures don’t have to be solid models as they are at last downgraded into two dimensional rib sections with interlocking details. As […]
