This lecture covers the fabrication process, focusing on 2D nesting and CNC fabrication. It explains how 2D nesting optimally orients shapes from 3D to 2D space, leading to efficient material usage. The CNC procedure involves various sub-routines like drilling, cutting, and milling, resulting in interconnected components. A real structure example from Lausanne Church demonstrates the application of nesting strategies, joinery techniques, and innovative snap-fit joints for assembly and disassembly of timber plates.
