DS ISO 1 is a neutral, highly legible sans-serif typeface designed as the default UI/brand font for a modern Design System (DS). It prioritizes clarity at small sizes, accessible character shapes, wide language coverage, and practical variable-font features to support responsive digital products and brand consistency across platforms.
In an age dominated by pixels, vector graphics, and high-definition displays, the physical act of technical drawing might seem like a relic of a bygone era. Yet, the blueprint remains the universal language of engineers and architects. For this language to be understood without ambiguity, its alphabet must be absolute. Enter —a typeface that, despite its unassuming name, serves as the typographic bedrock of international manufacturing and construction. More than just a collection of letters, DS ISO 1 is a tool of objectivity, ensuring that a drawing created in Tokyo can be fabricated accurately in Toronto.

Applying in CAD Software (e.g., CATIA) Access Toolbar : Open your drawing or annotation environment. If the Text Properties toolbar isn't visible, go to View > Toolbars > Text Properties
Conversely, symbols that represent fixed entities, mathematical constants, or descriptive labels are set in upright (roman) type. The most prominent example of this distinction is found in the notation of the speed of light, "c," and the imaginary unit, "i." While these are single letters, they are not variables; they are specific, defined constants. Therefore, ISO standards dictate they be written as upright " c " and upright " i " (or "j" in electrical engineering), rather than the italicized versions used for variables.
Notable omissions: lowercase letters (excluded for decoder complexity), brackets {}[] , backtick, tilde, and pipe.
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.
