2. 2EDT 300 - Elevations Objectives u List exterior elevation features. u Show elevation dimensions. u Show elevation symbols. u Draw typical exterior elevations.

3. 3EDT 300 - Elevations Elevations u An elevation is u an orthographic projection (drawing) u that shows one side of the building. u The term "elevation" usually refers to an exterior elevation. u Various interior elevations may be drawn, but they are usually considered to be details.

4. 4EDT 300 - Elevations Elevations u Elevations u Show the finished appearance of a given side of the building. u Show vertical height dimensions.

10. 10EDT 300 - Elevations Elevations u Four elevations are customarily drawn u One elevation for each side of the house. u More than four elevations may be required to describe some structures.

11. 11EDT 300 - Elevations Elevation Drawings u Elevation drawings provide u Height information about basic features of the house that cannot be shown very well on other drawings. u Exterior materials information such as u Siding and u Roof covering.

12. 12EDT 300 - Elevations Elevation Drawing Information u Elevation drawings must include: u Identification of the specific side of the house that the elevation represents. u Grades. u Finished floor and ceiling levels. u Location of exterior wall corners. u Windows and doors. u Roof features. u Vertical dimensions of important features. u Porches, decks and patios. u Material symbols.

13. 13EDT 300 - Elevations Elevation Identification u Identify each elevation as to the particular wall it represents. u North Elevation u South Elevation u East Elevation u West Elevation

14. 14EDT 300 - Elevations Elevation Identification u Two methods commonly used for identifying elevations u 1. Front, Rear, Right Side, and Left Side u 2. North, South, East, and West

15. 15EDT 300 - Elevations Elevation Identification u Front, Rear, Right Side, and Left Side designation is preferred by most designers. u There is a possibility of confusion when specifying directions.

16. 16EDT 300 - Elevations Elevation Identification u The right and left side elevations are determined by facing the front of the building. u The right side elevation is on the right side. (!) u Identify each elevation below the drawing to avoid confusion.

17. 17EDT 300 - Elevations Grade Lines, Floors, Ceilings u The reference point for most elevations is the grade line. u Study the plot or site plan to determine the existing grade along each exterior wall of the house. u If the existing grade is not satisfactory, a final grade line must be indicated on each elevation affected.

18. 18EDT 300 - Elevations

19. 19EDT 300 - Elevations Grade Lines, Floors, Ceilings u Indicate the desired elevation height of the grade at each corner of the house. u Record this information on u The Plot Plan u The Elevation Drawing if the site is not relatively level.

20. 20EDT 300 - Elevations Grade Lines, Floors, Ceilings u Below grade features should be drawn in hidden lines. u Foundation walls. u Footings. u Window wells (areaways).

21. 21EDT 300 - Elevations Grade Lines, Floors, Ceilings u Floor-to-ceiling height is an important feature of the elevation. u Two methods of representing this height are commonly used.

22. 22EDT 300 - Elevations

23. 23EDT 300 - Elevations Grade Lines, Floors, Ceilings u First Method: u Indicate the finished floor-to-finished ceiling distance. u The floor and ceiling are represented using a center line symbol. u First floor finished floor to finished ceiling is 8'-0" u Second floor finished floor to finished ceiling is 7'-6" or 8'-0”.

24. 24EDT 300 - Elevations Grade Lines, Floors, Ceilings u First Method: u For EDT 300, use THIS METHOD.

25. 25EDT 300 - Elevations Grade Lines, Floors, Ceilings u Second Method: u Show the construction dimension, measured from the top of the subfloor to the top of the wall plate. u The construction dimension u First floor 8'-1 1/2" u Second floor: 7'-7 1/2" or 8'- 1 1/2" u Carpenters usually prefer the this method because it does not require them to do any calculation.

26. 26EDT 300 - Elevations Grade Lines, Floors, Ceilings u Garage ceilings u minimum recommended height is 8'-O". u Basements u Minium clear headroom space of at least 6'-2”. u All beams and heating ducts must be above this height. u A full height ceiling is more desirable and should be specified where practical.

27. 27EDT 300 - Elevations Grade Lines, Floors, Ceilings u Most codes require that the top of the foundation wall be at least 8" above the grade. u This is to protect the framing members from moisture. u Also helps deter insect entry into home.

28. 28EDT 300 - Elevations Grade Lines, Floors, Ceilings u The garage floor u may be slightly higher than the grade, u but should be at least 4" lower than an interior floor when the garage is attached to the house.

32. 32EDT 300 - Elevations Walls, Windows, and Doors u All visible wall corners are shown on the elevation using object lines. u In rare instances it may be desirable to show hidden walls.

33. 33EDT 300 - Elevations Walls, Windows, and Doors u Exterior windows and doors must be included on the elevation. u Project from the floor plan for window and door location. u The vertical height is shown only on the elevation drawing.

34. 34EDT 300 - Elevations Walls, Windows, and Doors u Place tops of windows the same height as the tops of doors. u The lower face of the head jamb is considered the height of the opening. u Tops of doors and windows is usually 6'- 10" from the top of the subfloor.

35. 35EDT 300 - Elevations Walls, Windows, and Doors u Windows and Doors u Show sufficient detail on windows and doors to accurately indicate details. u If windows are hinged, show the swing using the proper symbol. u If the windows or doors have brick mold or other trim, then show this on the elevation.

36. 36EDT 300 - Elevations Walls, Windows, and Doors u Windows and Doors u Show the window and door identification symbols on the elevation plan and floor plan.

37. 37EDT 300 - Elevations Roof Features u Roof u Showing roof features on an elevation drawing is important. u The roof style and pitch are shown. u The chimney height and size are shown.

38. 38EDT 300 - Elevations Roof Features u The roof pitch may be indicated using the fractional pitch or slope triangle. u The slope triangle is usually preferred.

39. 39EDT 300 - Elevations Roof Features u The slope triangle can be thought of as u Rise to run u 5” vertical rise for every 12” horizontal run.

40. 40EDT 300 - Elevations Roof Features - Chimney u Chimneys u When they intersect the roof, they require more than one view to determine the points where they pass through the roof. u Draw the view where the roof slope is shown first. u This view will indicate where the chimney passes through the roof. u These points may then be projected to other views.

41. 41EDT 300 - Elevations Roof Features - Chimney u Chimneys u The chimney height above the highest roof point must be dimensioned. u A minimum height of the chimney above the ridge is usually 2'-0".

42. 42EDT 300 - Elevations Roof Features - Chimney u Other Items shown on elevation u Chimney flashing, u Roof covering material, and u Gable ventilators u are also shown on the elevation. u Use proper symbols and adequate dimensions and notes on the drawings.

43. 43EDT 300 - Elevations Dimensions, Notes, and Symbols u Elevation Drawing Dimensions u are mainly vertical height dimensions. u Dimension: u Thickness of the footing. u Distance from the footing to the grade. u Finished floor-to-finished ceiling distances. u Overhang width. u Height of the top of windows and doors. u Height of chimney above the roof.

44. 44EDT 300 - Elevations Dimensions, Notes, and Symbols u Other dimensions may be required: u Deck railing. u Retaining walls. u Planters.

45. 45EDT 300 - Elevations Dimensions, Notes, and Symbols u Notes u Include where additional information is needed. u Some typical elevation drawing notes: u Grade information. u Exterior wall material notation. u Roof covering material identification. u Fascia material. u flashing material. u Other notes may be required for specific situations.

46. 46EDT 300 - Elevations Dimensions, Notes, and Symbols u Symbols u are commonly used on elevations. u Roof Pitch Symbol u The roof pitch symbol is always shown u Exterior Wall Covering Symbol u The exterior wall covering is usually symbolized. u Brick, siding, etc

47. 47EDT 300 - Elevations Dimensions, Notes, and Symbols u Symbols u Show material symbols extensively on the front elevation. u Show materials sparingly on the remaining views. u Left u Right u Rear

48. EDT 300 - Elevations48 Procedure for Drawing Elevations

49. 49EDT 300 - Elevations Floor Plan vs Elevations u The floor plan u shows the width and depth of a house plan and u the interior features. u The elevations u show the width and height of the house and u its exterior features.

50. 50EDT 300 - Elevations Drawings u When designing a house u The floor plan is usually designed first. u The elevations are then projected and designed from the floor plan. u Following these procedural steps will insure an accurate and fast layout for the elevation design.

51. EDT 300 - Elevations51 Drawing Elevations

52. 52EDT 300 - Elevations Drawing Elevations - Step 1 u Tape the finished floor plan to the top of the drawing board, above a blank drawing format for the elevation drawings.

53. 53EDT 300 - Elevations

54. 54EDT 300 - Elevations Drawing Elevations - Step 2 u On the blank new sheet, lay out all the horizontal heights for: u The finish grade. u Floor line. u Depth and thickness of footings. u Window and door heights. u Ceiling line. u Eaves line. u Ridge line/board. u Top of chimney.

55. 55EDT 300 - Elevations

56. 56EDT 300 - Elevations Drawing Elevations - Step 3 u Project the length from the floor plan of: u Walls. u Windows. u Doors. u Chimney. u The lengths of these items have already been determined on the floor plan.

57. 57EDT 300 - Elevations

58. 58EDT 300 - Elevations Drawing Elevations - Step 4 u Darken in each feature. u Windows, doors, etc u Remove construction lines. u Complete the roof design u Add details such as: u Trim details. u Gable ventilators. u Window wells. u Dimensions.

59. 59EDT 300 - Elevations Drawing Elevations - Step 5 u Add dimensions, notes and symbols. u Draw material symbols legend as the last item since it may interfere with other information.

60. 60EDT 300 - Elevations Drawing Elevations - Step 6 u Check the drawing to make sure all features are shown. u Repeat these steps for every elevation. u Draw two elevations on one sheet if space permits.
