Centrolinead

The centrolinead was invented by Peter Nicholson, a British mathematician and architect, in 1814. It was used to construct 2-point perspective drawings where one or both vanishing points existed outside the drawing board. Draftsmen could use the instrument in pairs; one for each vanishing point on each side of the station point.
