Engineering Lettering

Lettering is an essential element in both traditional drawing and CAD drawing. Graphic communication is often not enough to completely describe an object. Lettered text is often necessary to provide detailed specifications about the drawn object. And there are a number of formal rules that apply to the placement of lettering.

Commercial Gothic, also called sans-serif Gothic, is the lettering style of most interest to engineers. It is plain and legible. While admittedly not as beautiful as many other styles, sans-serif letters are comparatively easy to make. They may be drawn in outline and then filled in. 

C.W. Reinhardt, formerly chief draftsman for Engineering News, developed alphabets of capital and lowercase inclined and “vertical letters, based on the old Gothic letters. For each letter, he worked out a systematic series of strokes. 

Reinhardt’s development of single-stroke letters was the first step toward standardization of technical lettering.

Architects and engineers have their own kind of lettering.
Students in these fields learn to letter by hand, even though they will be doing much of their work on the computer, because design sketches are always done in pencil, as are many other types of sketches such as preliminary drafts, and design ideas. Overview:

* Lettering must be neat and readable – Should use all capital letters * Tools
* Traditional hand sketching
* Computer Aided Drawing (a large industry producing computer packages they may have heard of in AutoCad, ProEngineer, SolidWorks)
* Media (how we record)
* Paper – helpful to know about Standard Sizes (Table 1) and Title Blocks * Alphabet of lines - examples of line types.
* The best pencil for lettering on most surfaces are the H, F, and HB grades. * Hold your pencil in the position shown. It should make approximately a 60o angle with the paper. * Freehand lettering is used in many...
