Which statement accurately describes a 3rd angle orthographic drawing?

• A. A working drawing showing each side of a design without perspective
• B. A method used only for electrical schematics
• C. A type of drawing that employs isometric techniques
• D. A representation that excludes dimensions

Answer: (A)

The statement that accurately describes a 3rd angle orthographic drawing is that it is a working drawing showing each side of a design without perspective. In 3rd angle orthographic projection, multiple views of an object are created, typically including the front, top, and side views, which illustrate the dimensions and details of the design clearly and precisely. This type of drawing is standard in engineering and design because it provides a comprehensive understanding of the object's geometry without the distortion that can occur in perspective drawings. The focus on showing each side of the design allows engineers and manufacturers to understand complex parts and their relationships, ensuring that all critical details are communicated effectively for accurate production or analysis.
