It should be noted that a pantograph consists of four rods that are joined together in order to form a parallelogram with the joints varying in relation to the scale of reproduction.
<h3>
Pantograph</h3>
In a pantograph, the mechanical assembly is based on the shape of a parallelogram.
It should be noted that the operation of a pantograph can be related to dilation as it has a fixed center and two points which are a drypoint that follows the contour of the original drawing, as well as a pen point that traces the reproduction in an enlarged or reduced form.
In order to enlarge a drawing, the index is positioned between the fixed center and the pen. Therefore, to reduce it, the pen is set between the fixed center and the index.
Lastly, to copy a drawing on the same scale, it can be deduced that the index and the pen are equidistant from the fixed center.
