3D CAD was originally developed not for drawing but for observing the shape of a 3D object. Accordingly, it is easy to construct a 3D body using 3D CAD, whereas 3D CAD sometimes leads unexpected printing of the measure of the body on the drawing sheets. Detailed information on the merits and demerits of 3D CAD in its applications to graphic science and drawing however is not understood yet. The adequacy of 3D CAD to the drawing is discussed in this report.
