Schematic Drawings are types of electrical or mechanical system diagrams. They are high-level diagrams that explain how something functions or how individual parts interact. We create standard symbols primarily using wiring diagrams, symbols, and lines. We generate electrical diagrams, such as schematic symbols, piping instrument diagrams, etc.
In a concept or early design, schematics are used to outline a design and its principles.
On a subway map, for instance, a dot is intended to represent a subway station. It is not intended for the dot to resemble the actual station. It aims to provide the viewer with information without unnecessary visual clutter.
In addition, a schematic diagram of a chemical process includes symbols representing the vessels, piping, valves, pumps, and other equipment in minute detail. It composes the system, emphasizing the functions of the individual elements and their interrelationships while obscuring their exact physical characteristics. In an electronic circuit diagram, the layout of the symbols may not correspond to the physical appearance of the circuit board. Instead of depicting the physical appearance of the circuit, the schematic attempts to capture its operation on a more general level.
