The Reflected Ceiling Plan is a type of architectural drawing that shows the view of a ceiling as seen from below, looking up. It is a two-dimensional representation of the ceiling, including all the elements such as lighting fixtures, ventilation grills, sprinkler heads, and any other features that are present on or above the ceiling. It provides a clear and detailed overview of the ceiling's layout, making it easier to coordinate with other trades and ensure that all necessary elements are included in the final design.
