In the case of a floor plan, the roof and upper portion of the walls may typically be omitted. In such views, the portion of the object above the plane (section) is omitted to reveal what lies beyond.
In other words, a plan is a section viewed from the top. interior features such as fireplaces, saunas and whirlpoolsĪ plan view is an orthographic projection of a three-dimensional object from the position of a horizontal plane through the object.appliances such as stoves, refrigerators, water heater etc.A top view or bird's eye view does not show an orthogonally projected plane cut at the typical four foot height above the floor level. It is a measured drawing to scale of the layout of a floor in a building. This symbol shows the location of the door in a wall and which way the door opens.Ī floor plan is not a top view or birds eye view. τὸ ἴχνος, íchnos, "track, trace" and γράφειν, gráphein, "to write" pronounced ik-nog-rəfi) was first described by Vitruvius (i.2) and included the geometrical projection or horizontal section representing the plan of any building, taken at such a level as to show the outer walls, with the doorways, windows, fireplaces, etc., and the correct thickness of the walls the position of piers, columns or pilasters, courtyards and other features which constitute the design, as to scale.įloor plan topics Building blocks įloor plans use standard symbols to indicate features such as doors. The art of constructing ground plans ( ichnography Gr. RCPs are used by designers and architects to demonstrate lighting, visible mechanical features, and ceiling forms as part of the documents provided for construction. This convention maintains the same orientation of the floor and ceilings plans – looking down from above.
Drawings are now reproduced using plotters and large format xerographic copiers.Ī reflected ceiling plan (RCP) 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. For example, it may denote the arrangement of the displayed objects at an exhibition, or the arrangement of exhibitor booths at a convention. The term may be used in general to describe any drawing showing the physical layout of objects. Plan view or planform is defined as a vertical orthographic projection of an object on a horizontal plane, like a map. Objects below this level are seen, objects at this level are shown 'cut' in plan-section, and objects above this vertical position within the structure are omitted or shown dashed. Similar to a map, the orientation of the view is downward from above, but unlike a conventional map, a plan is drawn at a particular vertical position (commonly at about four feet above the floor).
