Abstract
Mechanical drawings are prepared by projecting the outline of the object on to one or more planes. The lines of projection are always parallel in engineering drawings, so that two lines in the object which are parallel and of equal length appear of equal size in the drawing. For example, a set of four parallel edges of a cube will always appear as lines of the same length in an engineering drawing.
