▪ Not really a computer article, the author uses a CAD-like system of plotting the contours of an arched plate. The result is sort of a topo map of the plate that is used to rout the plate into terraces that are then faired into a finished plate. Mottola explains the drawing, not the machining. With 13 drawings.
