Scales, Symbols: Floor Plan, Materials in Section, and Door/Window Symbols
History of the Measuring System
Royalty determined units of measurementKing Henry I Yard measurement
King Edgar Inch measurement
King Charlemagne Foot measurement
The Architectural ScaleMeasures Feet and InchesTwo types or designs of scale divisions:Fully DividedOpenly Divided
The Architectural Scale
Makes large things small and proportionally accurateCommon floor plan scale is 1/4” = 1’- 0”Other proportions or measurements on the Architectural Scale1/8”, 3/16”, 3/4”, 1”, 3/32”, 3/8”, 1/2”
1 1/2” and 3”Full size measurement is the 16 scale, meaning 16 parts of an inch equaling 1/6”.
The16 Scale is used for Full Size and Half Size Measurements
Size Determination of a Scale
Example: ½’ = 1’-0”Reduce each side of the equation to same units and compare ½” = 1’-0” ½” = 12”½”/(½”) = 12” / (½”) 1 = 24 therefore scale size is 1/24
Sizes Compared to Scales1/8” = 1/96 size, 1/4” = 1/48 size
3/32” = 1/128 size, 3/16” = 1/64 size
Writing the Actual Measurement
Feet and Inch/fractions: 6’-7 1/2”Even feet no inches: 4’- 0”Feet and zero inches/fractions: 8’- 0 3/4”No feet only inches: 10”No feet only inches/fractions: 5 1/2”Only fractions of an inch: 3/4”
Architectural Symbols
Usually not in color
Material Symbols in Section Used to represent construction material when sliced or cut by cutting planeThe type of symbols used depends on the the scale of the drawingSymbols may vary with each office. Common material symbols designations have been derived by:1) Committee on Office Practice (AIA), 2)Task Force on Production Office Procedures North California Chapter AIA, 3)pamphlets, 4)manufacture literature, 5)textbooks, and 6)government agencies

Interior Door/Window SymbolsFor Interior doors there is no threshold at door wayCross lines at door swing and door intersectionLength of door on plan represents actual door size
Exterior Door/Window SymbolsThreshold is shown on all exterior door symbols

Drawing the Door Symbol
Floor Plan SymbolsPouche’ or Poche’ is a tone added to the walls to help them stand out on the plan. Options are: Straight line poche Freehand curved line poche Leave walls blank
DoThisOne
Poche’ added to Wall
Floor Plan SymbolsProfile line added to accent outside of wallUse .9 mm pencil, usually done at the last so graphite will not smear
Add Profile Line
Floor Plan Symbols
Other material symbols are also used along with the poche’, for example: brick and/or concrete
