Drawings that are used to guide the production of a product.

• A. Photorealistic CAD-based models
• B. Drawings for production
• C. Working drawings
• D. Air-drying

Answer: (C)

The main idea is that production-ready drawings must convey precise, complete instructions that a manufacturer can follow. Working drawings are specifically the detailed documents that include exact dimensions, tolerances, material specifications, finishes, part numbers, and assembly or manufacturing notes. They translate the design into actionable guidance for fabricators, machinists, and inspectors, ensuring the product can be produced consistently and correctly. A photorealistic CAD model, while great for visualizing appearance, typically doesn’t include all the necessary manufacturing details like tolerances and materials, so it isn’t the primary guide for producing parts. The phrase “drawings for production” is vague, whereas working drawings are the established set used to guide the actual making and assembly of the product.
