Which symbol on a blueprint indicates a casement window?

• A. An elongated rectangle
• B. A solid circle
• C. A rectangle with a hinge line
• D. A square

Answer: (C)

The symbol that indicates a casement window on a blueprint is a rectangle with a hinge line. This representation effectively communicates the fundamental design and operational characteristics of a casement window, which is hinged on one side and swings open outward, much like a door. The rectangle illustrates the frame of the window, while the hinge line specifies the pivot point, indicating how the window functions. This clarity is essential for builders and contractors to accurately interpret the plans and execute the design as intended.

Other symbols on blueprints, like the elongated rectangle or solid circle, represent different types of elements and do not convey the specific details associated with a casement window. A square may denote other architectural features or fixtures but lacks the distinctive details that identify the operational nature of a casement window.
