Technical lettering
From Wikipedia, the free encyclopedia
Not to be confused with technical writing.
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.
There are two methods of forming letters:
- Freehand lettering is done without the assistance of tools. To regulate lettering height, commonly 3 mm (1/8"), guidelines are drawn.
- Mechanical lettering is done using tools such as lettering guides and computer-aided design software.
