Section Layout

introduction
Introduction
  • Drawing sections is accomplished in seven major stages
    • Follow the step-by-step procedures
      • Sections can be easily drawn and understood
      • Read through each stage, and carefully compare the instructions with the corresponding illustrations
stage 1 evaluate needs
Stage 1: Evaluate Needs
  • Differences in required construction include:
    • Right side of the plan is one story, and left side is two story
    • Rear at right is a stick floor, and front is a concrete slab
    • Left side of the roof is a vaulted truss, and right side is a standard truss
stage 1 evaluate needs cont d
Stage 1: Evaluate Needs (cont’d.)
  • Minimum of two full sections is required to provide needed information
    • One cuts through the family room and kitchen
      • Shows concrete floor, walls, upper-floor cantilever, and truss roof
    • A full section is needed through the garage
      • Shows concrete and wooden floor construction
    • Partial sections show stairs and vaulted roof over bedroom 1
stage 2 lay out the section
Stage 2: Lay Out the Section
  • Use construction lines for entire stage
    • Use a nonreproducible blue pencil or a 6H lead
      • If working with AutoCAD, place materials on a layer (e.g., OUTL)
  • Section includes layouts for:
    • Concrete slab foundations
    • Walls
    • Truss roof
stage 3 finished quality lines for structural members only
Stage 3: Finished-Quality Lines for Structural Members Only
  • Drawing with finished-quality lines
    • Start at the roof and work down
  • Steps followed are divided into:
    • Truss roof
    • Walls
    • Upper walls and floor
    • Lower walls
    • Foundation
stage 3 finished quality lines for structural members cont d
Stage 3: Finished-Quality Lines for Structural Members (cont’d.)
  • Continuous members
    • Diagonal cross (X) in the member
  • Blocking
    • One diagonal line (/) through the member
  • Members are also be drawn with different line qualities
    • Thin, bold, and very bold
stage 4 drawing finishing materials
Stage 4: Drawing Finishing Materials
  • Material drawn in this stage seals exterior from weather and finishes the interior
    • Start at the roof and work down to foundation
    • Use thin lines for this stage unless otherwise noted
stage 5 dimensioning
Stage 5: Dimensioning
  • Leader lines should be thin
  • Lettering should be aligned
    • If using AutoCAD, place dimensions using the DIM command and ANNOTATIVE feature
stage 6 lettering notes
Stage 6: Lettering Notes
  • Place guidelines around drawing perimeter
    • Align required notes on the guidelines
      • Typically, the primary section will be fully notated, and other sections will have supplemental notes
    • General notes are included for:
      • Roof
      • Walls
      • Upper floor and foundation
stage 7 evaluating your work
Stage 7: Evaluating Your Work
  • Run a print, and evaluate it for accuracy and quality
    • Compare with someone else’s
    • Use a checklist
    • Get away from the drawing for an hour or two and then go back to it
section trusses checklist
Section-Trusses Checklist
  • Refer to the text for a complete truss checklist, including:
    • Plotting
    • Drawing
    • Dimensions
