Which symbol would be used for indicating a standard hinged door?

• A. A sliding door
• B. A bifold door
• C. A cased doorway
• D. A regular door symbol

Answer: (D)

The symbol used for indicating a standard hinged door is a regular door symbol. This symbol typically consists of a simple rectangle with an arc that indicates the direction in which the door swings. In architectural and interior design drawings, this representation is essential for conveying how a door operates within a space, including factors like clearance and accessibility.

In contrast, other door symbols represent different types of doors and their functionalities. A sliding door symbol would depict a door that moves horizontally along a track, while a bifold door symbol illustrates a door that is made up of two panels that fold against each other. A cased doorway symbol indicates an opening without a door, often highlighting an archway or entryway rather than a functional door. Understanding these symbols and their appropriate contexts is crucial for effective communication in design documentation.
