A floor plan (floorplan, floor-plan) in architecture and building engineering is a diagram of a room, a building, or a level (floor) of a building as if seen from the above (i.e. a map). You may also think of it as a "top view" or "bird's eye" view of one floor in a building. Technically, the floor plan shows the walls and fixtures in a building at the height of one meter (or 4'-0") "above the finished floor" (AFF).
The term may be used in general to describe any drawing showing the physical layout of objects. For example, it may denote the arrangement of the displayed objects at an exhibition, or the arrangement of exhibitor booths at a convention. A copy of an original floor plan drawing is traditionally called a blueprint. Now drawings are reproduced using plotters and large format xerographic copiers.
Plan view or "planform" is defined as a vertical orthographic projection of an object on a horizontal plane, like a map.
It is also called a "plan" in architectural terms, as opposed to "elevation" which means how the object will look when seen from a side, or a "cross section" where the building is shown cut along an axis to reveal the interior. A "reflected ceiling plan" shows a view of the room as if looking from above, through the ceiling, at a mirror installed one foot below the ceiling level, which shows the reflected image of the ceiling above. This convention maintains the same orientation of the floor and ceilings plans - looking down from above.Template:Architecture-stub
