The Layer Chair is designed as an example of working with large organic surfaces on the CNC Router. The parametric Grasshopper definition enables you to input any profile curve you like, and the system outputs new milling curves. So, you can create the perfect chair for you. The parametric system lets you chance your material thickness, milling bit size, desired chair width and so on. It also possible to change the shape language of the chair by adjusting the size of the inside and outside fillets.
