Elevation

  An elevation is a scaled drawing that shows a vertical surface or plane seen from a point of view perpendicular to the viewers'picture plane.An elevation is also a type of orthographic multiview drawing.The various elevation views include the front,sides,and rear.Planes perpendicular to the picture plane are seen on edge,and other angles are seen foreshort-ened.Elevations are drawn as straight-on views,so there is no distortion as in a perspective or isometric drawing.Architectural elevations illustrated the finished appearance of an exterioror interior wall of building in it. 

  Elevations serve as a primary source to show heights,materials,and related information that cannot be seen in floor plans,sections,or other drawings.For example,a lavatory bas and vanity shown on a floor plan gives no information about the number,heights,and sizes of doors and drawers located beneath the basin unit, An elevation is drawn to convey this information.Elevations are drawn as exterior or interior views of a building,or they might be specialized views of objects such as furniture or free-standing cabinetry.Elevations generally show:

1. Object profiles and finish materials.

2. Relationships of different parts of objects such as doors,drawers,and top surfaces of a cabinet.

3.Vertical dimensions of an object that cannot be found in a plan view. In some cases,horizontal dimensions are also shown for clarity.     

     

Exterior Elevations:-

Exterior elevations illustrate the finished appearance of an exterior or wall of a building.They convey the types of materials proposed,types of doors and windows,the finished grade,roof,slope,foundation,flootings,and selected vertical dimensions.Elevations assist the designer in visualizing how proposed the  door and window types and locations on the floor plan will influence the apperance and style of the structure.

Exterior elevations are identified with a title and scale.Generally exterior elevations are titled according to the compass direction they are facing,either North Elevation.East Elevation,South Elevation,or West Elevation,if a building is not facing true,north,the side that is oriented the most nearly north is identified as such.Then the other elevations are titled according to the compass direction most closely related to them.In some cases,exterior elevations are titled Front,Rear,Left,and Right.     

In most cases,architects and engineers draw exterior elevations.However,interior designers may be required to draw exterior elevations for residential or small commercial projects,such as retail store facades,as shown in it.When remodeling a building or adding space to an exisiting structure,it may be necessary for the interior designer to draw partial exterior elevations for clarity and understanding. 

Interior Elevations:-

An interior elevation is a vertical projection of a wall  or other surface inside a building and shows the finished appearance of that wall or surface.It is seen as a straight-on view of the surface,as there is not a lot of need to show depth.Curves,spheres,and slanted surfaces disappear on the flat vertical plane of an elevation as illustrated in it.However,depth can be indicated if desired by adding shading and shadowing.

  In most cases,the real importance of an elevation is so to show vertical elements,dimensions,and details that cannot be explained clearly in plan view.Interior elevations are particularly useful for showing the height of openings in a wall,materials and finishes of a wall,vertical dimensions,and details that cannot be explained clearly in plan view.Interior elevations are particulary useful for showing the height of openings in a wall-mounted items (such as shelves and/or cabinets),location of switches,and special wall treatments.For example,an interior wall elevation might show the height of a grab bar and the location (height and cut-out size required) of a recessed tissue dispenser in a commercial bathroom,as illustrated in it.
