It is a specific style of lettering that ensures clarity, legibility, and uniformity in the presentation of information on engineering drawings.

The "1-3-3" refers to the proportions used in this lettering style. The height of uppercase letters is typically one unit, while the height of lowercase letters is three units. The width of all letters, both uppercase and lowercase, is also three units. This proportional system helps maintain a balanced and aesthetically pleasing appearance of the text on the drawing.

By using the 1-3-3 engineering lettering style, engineers and drafters can create drawings that are easy to read, understand, and interpret. It ensures that the text is clearly visible and distinguishes it from other elements on the drawing, such as dimensions, annotations, or labels.
