🔎 Symbols & Plan Notes

• Casing profiles: labeled by code (e.g., C-1, C-2) in door/window schedules.
• Baseboards: continuous line at wall base, note for height/profile.
• Crown molding: triangle or hatch at ceiling/wall junction.
• Millwork elevations: detailed drawings for cabinets, shelving, paneling.
• Finish schedule: lists materials, species, paint/stain, and sheen.

📐 Key Calculations

• Baseboard length: total wall perimeter – door openings.
• Crown molding: room perimeter, add 10% waste for miter cuts.
• Door casing: (height × 2 + width × 1) × # of doors.
• Window casing: (2 × height + 2 × width) × # of windows.
• Cabinetry: linear footage × depth × height = board feet.
• Stair trim/skirt: run length + riser height per stair × # of treads.

⚡ Quick Reference

• 🚪 Interior door casing width: 2 ¼" standard (3 ½"+ for premium).
• 📏 Baseboard height: 3 ¼" builder grade, 5 ¼–7 ¼" upscale.
• 🪵 Common species: MDF (painted), Pine (stained), Oak, Maple, Poplar.
• 🔩 Fasteners: 15–16 ga finish nails for casing/base, 18 ga brads for trim.
• 🎨 Finish coats: 1 primer + 2 paint coats or 2 stain + 1 clear sealer.
• 🪛 Joint type: coped joints for inside corners, miter for outside.

📝 Self Test

1. How do you calculate total casing needed for 20 standard interior doors?
2. What’s the difference between a coped joint and a miter joint?
3. What is the standard ADA baseboard height? (trick — not an ADA spec, but good to know common practice)
4. How much waste should you add for crown molding cuts?
5. Which nail gauge is commonly used for baseboards?

(Answers: 1) (2 × 6'-8" + 3') ≈ 16.3 LF × 20 ≈ 326 LF, 2) Coped = cut to fit profile, miter = angled cut, 3) Not ADA, typical 3–5", 4) ~10%, 5) 15–16 ga finish nails)
