Technical lettering is the process of forming letters, numerals, and other characters in technical drawing. It is used to describe, or provide detailed specifications for, an object. With the goals of legibility and uniformity, styles are standardized and lettering ability has little relationship to normal writing ability. Engineering drawings use a Gothic sans-serif script, formed by a series of short strokes. Lower case letters are rare in most drawings of machines

Methods of forming letters 1. Freehand lettering is done without the assistance of tools. To regulate lettering height, commonly 3 mm (1/8"), guidelines are drawn. 2. Mechanical lettering is done using tools such as lettering guides, templates, or using a small mechanical pantograph referred to by the Keuffel & Esser trademark "Leroy" 3. Modern drawings are lettered with computer-aided design software
Serif Serif lettering styles are letters that have tails on them. If you examine a font on the computer or text in a book, you will notice that some letters have tails and some consist of straight lines. Popular serif fonts or letter styles include Times New Roman, Bodini and
Baskerville. Serif fonts are usually easy on the eyes when reading and work well for body text. Serifs originated in the Latin alphabet with inscriptional lettering—words carved into stone in Roman antiquity. The explanation proposed by Father Edward Catich in his 1968 book The
Origin of the Serif is now broadly but not universally accepted: the Roman letter outlines were first painted onto stone, and the stone carvers followed the brush marks which flared at stroke ends and corners, creating serifs. Another theory is that serifs were devised to neaten the ends of lines as they were chiseled into stone.
