Instead of drawing a pump, valve, or motor from scratch for every new project, engineers pull these pre-made objects from the library. These objects are often more than just static pictures; they are typically "smart" objects linked to tags that change color, shape, or animation based on process conditions (e.g., a motor turning green when running and red when faulted).
