Here I am testing the nesting. 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 it. 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 the WorldXY…

After a reviewing a short story of digital architecture from Branko Kolarevic, we looked at the roots of the theory and the concepts derived from it such as digital fabrication, building information modeling and parametric modeling. After a short brief, we’ve discussed about the final projects. Next week, we’ll start studying final projects and start to look at individual problems developed from them. Final submissions will highly be related with their design problem; it might be only digital animations, or…

Nowadays, I found myself back into traditional hand sketching. Several failed attempts on Grasshopper led me back there. NURBS (and Grasshopper) somehow limits our conception of surfaces to four-cornered (or two-directional) manifolds. Although it sounds like limiting our designs, having four-cornered component spaces has still lots of experimental fields for designers. Escher is a cult person, who transforms the euclidean coordinate system to meet his design intentions. There are lots of interesting research about him, and he shows us how…

A previous work showed a method to create interlocking structures 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, and the other is the bottom. It was a small modification at the beginning; to replace the “extrude” component with an “edge surface” component. But the interlocking details are now different at each intersection, so another modification is made to the drawing of the rectangles….

It has been a tough problem for me, for the last two days. A parametric model of an interlocking structure (sometimes also called egg-crate, waffle, or contouring structure) can be created easily in Grasshopper using a Contour component. In addition, you need 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…

NURBS surfaces by nature, like four-corner topologies with U and V directions. Şebnem Yalınay Çinici has formulated a tectonic exercise of “Primitive Hut”, which in my point of view is a tough geometric challenge; a subdivision on a real three-corner manifold. That seems very easy at the beginning as both Rhinoceros and Grasshopper are able to create surfaces with three corners, by either lofting, meshing, or edge curve methods. However, those surfaces, then cannot be used to develop sub-surfaces because of…
