Which of the following is NOT a type of engineering drawing?

Literary sketches are not a type of engineering drawing because they are typically associated with the arts and literature, reflecting ideas or concepts in a more abstract and creative manner rather than adhering to the technical standards and conventions of engineering. In engineering, drawings serve specific functional purposes and communicate detailed information about components, systems, and processes essential for construction, manufacturing, and maintenance.

In contrast, architectural blueprints, mechanical drawings, and electrical schematics are all established forms of engineering drawings. Architectural blueprints detail the specifications and layouts of buildings, mechanical drawings focus on the design and specifications of mechanical components, and electrical schematics depict the electrical circuitry and relationships in an electrical system. Each of these types of drawings follows strict guidelines and standards to ensure clarity and precision in the communication among engineers, architects, and technicians.
