Engineers use ISO 2768 to define the allowable deviation for linear and angular dimensions. Without general tolerances, every single dimension on a blueprint would require an individual ± value. This would make drawings cluttered and difficult to read. By referencing "ISO 2768" in the title block, a manufacturer knows exactly how much "wiggle room" they have for non-critical features.
