What does a cased doorway symbol signify on a blueprint?

• A. A concealed entry
• B. A door with no framing
• C. A standard entry without a door
• D. A window opening

Answer: (C)

A cased doorway symbol on a blueprint indicates a standard entry without a door. This type of opening is typically enclosed with trim, giving it a finished appearance but does not include a door. Cased doorways are often used in spaces where a door is not necessary, allowing for an open flow between rooms while still providing a defined entryway. The trim around the opening highlights the architectural detail without obstructing the passage, enhancing the overall design aesthetic of the interior space.

The other choices do not accurately reflect the function of a cased doorway. A concealed entry suggests an entrance that is hidden or not immediately visible, which does not align with the nature of a cased opening. A door with no framing would imply a less defined entry, lacking the structure that a cased doorway provides. A window opening, meanwhile, signifies an entirely different architectural element, typically used for natural light and views rather than passage between spaces.
