U+2331 "⌱" Dimension Origin Unicode Character

U+2331 "⌱" Dimension Origin is a graphic symbol defined within the Miscellaneous Technical block, specifically designed to represent the starting point or reference datum for dimensions in technical drawings, engineering blueprints, and CAD systems. It visually resembles a crosshair or a set of orthogonal axes emanating from a central point, often used to indicate the absolute coordinate system against which all other measurements on a diagram are relative. While part of the APL programming language symbols, in a general technical context it functions as a standard notation for establishing spatial orientation and measurement baselines.
