"Building blocks A schematic drawing of an open door, seen from the top, with a curved line that shows a quarter-circle space on the floor that the door travels over when it opens Floor plans use standard symbols to indicate features such as doors. This symbol shows the location of the door in a wall and which way the door opens. A floor plan is not a top view or birds eye view. It is a measured drawing to scale of the layout of a floor in a building. A top view or bird's eye view does not show an orthogonally projected plane cut at the typical 4 foot height above the floor level. A floor plan could show:[1] Interior walls and hallways Restrooms Windows and doors Appliances such as stoves, refrigerators, water heater etc. Interior features such as fireplaces, saunas and whirlpools The use of all rooms Plan view A plan view is an orthographic projection of a 3-dimensional object from the position of a horizontal plane through the object. In other words, a plan is a section viewed from the top. In such views, the portion of the object above the plane (section) is omitted to reveal what lies beyond. In the case of a floor plan, the roof and upper portion of the walls may typically be omitted. Roof plans are orthographic projections, but they are not sections as their viewing plane is outside of the object. A plan is a common method of depicting the internal arrangement of a 3-dimensional object in two dimensions. It is often used in technical drawing and is traditionally crosshatched. The style of crosshatching indicates the type of material the section passes through. 3D Floor plans A 3D floor plan can be defined as a virtual model of a building floor plan. It's often used to better convey architectural plans to individuals not familiar with floor plans. Despite the purpose of floor plans originally being to depict 3D layouts in a 2D manner, technological expansion has made rendering 3D models much more cost effective. 3D plans show a better depth of image and are often complimented by 3D furniture in the room. This allows a greater appreciation of scale than with traditional 2D floor plans."
