  1. Architectural (Residential) DraftingDT 1100 Scales, Symbols: Floor Plan, Materials in Section, and Door/Window Symbols

  2. Architectural Scale

  3. History of the Measuring System • Royalty determined units of measurement • King Henry I • Yard measurement • King Edgar • Inch measurement • King Charlemagne • Foot measurement

  4. The Architectural Scale • Measures Feet and Inches • Two types or designs of scale divisions: • Fully Divided • Openly Divided

  5. The Architectural Scale • Makes large things small and proportionally accurate • Common floor plan scale is 1/4” = 1’- 0” • Other proportions or measurements on the Architectural Scale • 1/8”, 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”.

  6. The16 Scale is used for Full Size and Half Size Measurements

  7. 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

  8. Sizes Compared to Scales 1/8” = 1/96 size, 1/4” = 1/48 size 3/32” = 1/128 size, 3/16” = 1/64 size

  9. 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”

  10. Scale Chase Time!

  11. Architectural Symbols • Architectural Materials in Section, Door and Window Symbols, and Floor Plan Practice using Symbols

  12. Usually not in color

  13. Material Symbols in Section • Used to represent construction material when sliced or cut by cutting plane • The type of symbols used depends on the the scale of the drawing • Symbols 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

  14. Material Symbols in Section

  15. Other Material Symbols • A. Wood frame wall • B. Small scale masonry • C. Large scale double wythe brick wall • D. Concrete masonry • E. Steel tube • F. Steel S or W shape • G. Poured concrete • H. Batt Insulation • J. Rigid insulation • K. Small scale plywood • L. Large scale plywood • M. Soil/Earth • N. Gravel

  16. Other Material Symbols • P. Wood and timbers in end view • Q. Small scale steel in section • R. Large scale steel in section • S. Laminated timbers in end view • U. TJI side and end • V. Open-web trusses

  17. Interior Door/Window Symbols • For Interior doors there is no threshold at door way • Cross lines at door swing and door intersection • Length of door on plan represents actual door size

  18. Exterior Door/Window Symbols Threshold is shown on all exterior door symbols Outside

  19. Drawing the Door Symbol Demo on the Board

  20. Poche’ added to Wall Floor Plan Symbols • Pouche’ 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 Do This One

  21. Add Profile Line Floor Plan Symbols • Profile line added to accent outside of wall • Use .9 mm pencil, usually done at the last so graphite will not smear

  22. Brick Added to Frame Floor Plan Symbols • Other material symbols are also used along with the poche’, for example: brick and/or concrete

  23. Symbol Assignment

  24. Symbol Exercise Handout BATT (LARGE SCALE)

  25. Example of Exercise RUBBLE CONC BLK

  26. Lab Time to Work on Assignments
