• A drafting machine allows easy drawing of parallel lines over the paper.
• Drafting machines were present in the design offices of European companies since the 1920s.
• Drafting machines use pre-calibrated scales and built in protractors to allow accurate drawing measurement.
• Various types of drafting machine may be attached to the board surface to assist the draftsperson or artist.
• The original logo was most likely created on a drafting table with a drafting machine and colored pencils.
• Drafting machines are devices that aid manual drafting by combining drawing boards, straightedges, pantographs, and other tools into one integrated drawing environment.
• Modern drafting tables come equipped with a drafting machine that is supported on both sides of the table to slide over a large piece of paper.
• With the development of computer-aided design ( CAD ), the use of drafting machines, especially in the professional sector, has drastically declined, supplanted first by inkjet printers.

• With the drafting machine one can perform a series of drawing operations that otherwise could only be achieved with a much more complex use of the classic ruler parallel lines, orthogonal lines, inclined lines according to a preset angle, measurement of angles, etc.
• It was Electronic Drafting Machine ( EDM ), sold to Control Data and known as " Digigraphics ", which Lockheed used to build production parts for the C-5 Galaxy, the first example of an end-to-end CAD / CNC production system.
• Traditionally, steel detailing was accomplished via manual drafting methods, using pencils, paper, and drafting tools such as a parallel bar or drafting machine, triangles, templates of circles and other useful shapes, and mathematical tables, such as tables of logarithms and other useful calculational aids.
• A solution to these problems was the introduction of the mechanical " drafting machine ", an application of the pantograph ( sometimes referred to incorrectly as a " pentagraph " in these situations ) which allowed the drafter to have an accurate right angle at any point on the page quite quickly.
