• the tracing instrument When the tracing instrument is placed on the surface of a material where we want to act, we assume that it can be manipulated / moved with one hand without detaching it from the support, c 'that is, by dragging it. This is why we prioritize first the "sliding system” and then when required, by pressure exerted above the main body, to activate the "gripping system".
