This is a tutorial on how to CAD an existing design in Fusion 360. I borrowed the design from the wonderfully talented folks at Unto This Last. Their design is here: https://www.untothislast.co.uk/collections/chairs/products/facet-chair
I have no intention of fabricating this chair, as it is not my design.
