Blueprint View Types
  • Plan Views
  • Orthographic/Perspective
  • Detail Views
  • Contour/Topographic Views
  • Cross-sections
  • Profiles
  • Plot Plans

13
Typical Architectural Plan View
14
Orthographic Views/Drawings
  • all construction drawings use orthographic
    drawings
  • projected at right angles
  • more detail can be shown
  • start with the front view
  • drawn to true size or scale

15

16
Perspective View/Drawings
  • most realistic
  • receding lines meet at vanishing points
  • one - point
  • two - point

17
Perspective Drawings
18
Detail Views
  • Certain features can not always be clearly shown
    on construction drawings.
  • Require a large scale illustration to show all of
    the details.
  • May be placed on the same sheets as the plan or
    elevation views or on separate sheets.

19
Detail Views
20
Topography Contours
  • Contour Lines identify the ground elevation.
  • All points along a single contour line have the
    same elevation.
  • The interval between contours can represent any
    convenient distance. (i.e. 1, 2, 5, etc)
  • Topography is the location and elevation of
    features, consisting of both natural and man-made
    objects.

22
Cross Sections
  • Cross sections show the inside of a structure,
    or the elevations of the earth and structures
    along a station.
  • Used heavily in earthworks and highway
    construction.
  • Provided for features whose construction is not
    shown clearly on plan or elevation drawings.

23
Example of Cross Section
24
Profiles
  • Profiles are vertical sections through a
    topographic map that shows the earths surface at
    any location along an alignment.
  • Profiles often have a vertical exaggeration in
    order to show more detail of the surface.

26
Plot Plans(Site Plans)
  • View from above the property that illustrates
    location of building on the lot.
  • Lot and block number or address
  • Bearing and length of property lines
  • North arrow
  • Dimensions of front, rear and side yards.
  • Location of other accessory buildings
  • Location of walks, drives, fences, etc
  • Location of Utilities, and easement setbacks
  • Elevations at various locations
  • Etc
