In mechanical engineering, a datum feature symbol specifies a physical surface or feature used to establish a "datum" (a reference point or plane) for measurements.
This feature connects symbol properties (like size or color) directly to values in a data table, allowing for automated, data-rich map styling. symbol
This feature lets users display variations of a single symbol within a project without needing to delete and replace it, preventing the accidental disconnection of wires.

These are components that dynamically alter geometry (e.g., adding a dash or offset) for visual purposes only without changing the actual data. In mechanical engineering
This feature allows you to create multiple instances of a symbol that remain linked to a master, but with the flexibility to override certain properties like color or stroke without breaking that link. ArcGIS (Symbol Effects & Attribute-Driven Symbology):
