[Entry under construction]
This is a piece of urban furniture, developed through a process of collaborative design using digital design and digital fabrication tools. The piece works as an urban bench. It can be used as well as a small stage. It is built in 12 mm plywood, using a simple contour/section technique.
Dimensions: 2418 mm x 3180 mm x 642 mm
It is in the way of being parametrized [with Grasshopper] so that it can be adapted to different situations and sites. The design was developed within the Fabbing CC project, that took place in Caceres [Spain].
As it is one of our first tries with these object size the piece has to be considered a beta version. Improvements to be made include  the redesign of joints to make the press fit process smoother and more comfortable and  to include some kind of pieces in the joints that keep the sections in their position once they are there, and  a better design of the contact between the piece and the ground, that allows [a] for an easier assemblage process, [b] for easy adjustment to uneven ground, and [c] for protection from ground humidity affecting the plywood;  general dimensions can be improved too in order to have a more efficient use of the size of plywood sheets [especially concerning horizontal pieces. These piece was designed for a specific site and position that conditioned our dimensions, which were not very efficient.

Rhinoceros file corresponds to version 4.0 SR8.
Assemblage with these cutting files is rather difficult because of the high friction with the long joints. A very flat base is strongly recommended. Plywood sheets should be as flat as possible.
As a guide for assemblage main sections in both directions are separated 360 mm from one another. In the transversal dimensions secondary sections are separated 180 mm from each other.
Nesting can also be improved. With these sizes it should be possible to use 15 2400 x 1200 sheets instead of the 17 in the cutting file attached.
The images describe the recommended assemblage process.
In a next version we will incorporate the suggested improvements.
