From a functional design perspective, DS ISO 1 prioritizes legibility over aesthetics. Note the distinctive uppercase 'I' (eye) and lowercase 'l' (el), which are often confused in other fonts; in DS ISO 1, the 'I' has serifs or distinct horizontal bars, while the 'l' remains a simple vertical line. The number '0' is typically narrower than the capital 'O', and often features a slash or a distinct geometric contrast to avoid confusion with the letter. The height of lowercase letters (the x-height) is proportionally large relative to the capitals, maximizing readability at small sizes on crowded mechanical drawings. There is no ornamentation, no stylistic flair—only the pure, unadorned communication of dimension and quantity.
DS ISO 1 is an font with TrueType format outlines, designed to adhere strictly to the ISO 3098 series of standards. These standards define the requirements for lettering used on technical drawings and associated documents, ensuring maximum legibility and uniformity across global engineering projects.

The typeface includes four distinct variations: Regular, Italic, Bold, and Bold Italic. Because bold formatting is absent from the original ISO 3098 standard documentation, Dassault Systèmes engineering applied a calculated formula to achieve weight: the Bold and Bold Italic variants feature a precise relative to the Regular style.
