  1. Chapter 37 Section Layout

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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

  7. 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

  8. 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

  9. Stage 5: Dimensioning • Leader lines should be thin • Lettering should be aligned • If using AutoCAD, place dimensions using the DIM command and ANNOTATIVE feature

  10. 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

  11. 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

  12. Section-Trusses Checklist • Refer to the text for a complete truss checklist, including: • Plotting • Drawing • Dimensions
