Orientation

• Four elevations are normally projected by
  extending lines outward from each wall of the
  floor plan.
• When each elevation is classified according to
  their location, they are called the front, rear,
  right, and left elevations.

Auxiliary Elevations

• When a floor plan has walls that are not at right
  angles to one another, then an auxiliary
  elevation may be necessary to clarify the true
  size of the elevation.
• All you with bay or bow windows

Steps in Projecting Elevations (1 of 5)

• Step 1
• Using the floor plan, project the vertical lines
  that represent the main lines of the building.
• These lines show the overall length or width of
  the building.

Steps in Projecting Elevations (2 of 5)

• Step 2
• Measure and project horizontal lines that
  represent the height of the ground line, footing,
  doors, tops and bottoms of windows, chimney,
  siding, breaks, planters, and other key features.

Steps in Projecting Elevations (3 of 5)

• Step 3
• Complete the basic elevation, first develop the
  roof elevation projection.
• To determine the height of the eaves and ridge
  line, the roof slope must be established.

• Step 4
• Add detail and symbols, such as indicating door
  and window trim, brick or siding, and roofing
  materials.
