Wood Ceiling Framing Simulator

Draw the room → auto-calc battens, fiber-cement boards, hangers →
Print an A4 quote.

Living room, dining room, hallway — what used to take an afternoon now takes 30 seconds. Main + sub battens auto-align with board seams, hangers distribute evenly, and you can compare 4×8 vs 3×6 board specs to see which wastes less.

Included in Personal plan — one key unlocks all 26 furniture templates.

The 4 worst things about wood ceiling work

Exactly what this tool was built to fix

🧮

Adding up batten meters is dizzying

12-ft main battens, sub battens criss-crossing one by one, and rooms aren't perfect rectangles. Miss one and you're back at the lumber yard.

📐

Board seams missing the battens

Fiber-cement seams float between battens → unsupported edges, cracks by year-end. Aligning them by hand is exhausting.

📦

Order 4×8 or 3×6 boards?

Different prices, different waste. Guessing usually overshoots by 20%.

📄

Quoting means opening Excel again

Once you finish counting, you still type Excel, paste a logo, format A4. Change a dimension and redo it all — half a day gone.

What this tool does

Room shape → batten BOM → quote, end to end

📐

Room shape: rectangle / L / U / bay window

Drag length & width, L-shape inner corners, U-shape, pull bay windows out separately. 2D recalc live, 3D structure live.

🪵

Main + sub battens auto-laid

Main 60×30, sub 30×30, spacing 30/45/60 cm tunable. Auto-tiles across the whole room.

📦

Auto board layout

Switch 4×8 vs 3×6 specs side by side. Seams snap to batten centerlines — edges always supported.

🔗

Even hanger distribution

Hangers auto-laid by room length & width, 60–90 cm range, cross-joints emphasized for 3D legibility.

🎛️

3D 8-layer toggles

Slab / hangers / main battens / sub battens / boards / joints — toggle each. Clients grasp install order at a glance.

🧾

A4 quote + CSV BOM

Client info, line items, totals, terms — one A4 page. BOM exports to CSV for the crew.

Parameters you can tweak

The algorithm auto-calculates battens, board seams, hanger spread.

Room shape (rectangle / L / U / bay window)

Live 3D as you drag length/width, L/U inner corners tunable, bay windows pulled separately.

Ceiling height

Distance from original slab to wood ceiling — hanger length is auto-calculated.

Main batten spacing

30 / 45 / 60 cm presets. The system back-solves from board short edge so seams always land on batten centers.

Sub batten spacing

30 / 45 cm presets. Bigger spans auto-upgrade to heavier battens.

Fiber-cement board spec (4×8 / 3×6)

Toggle to see which spec wastes less — 4×8 means big sheets and low waste; 3×6 ships easier.

Hanger spacing

60–90 cm range, auto even distribution. The system warns if a span exceeds 90 cm.

Trim / molding (optional)

Add perimeter molding (PS or wood), with door openings auto-deducted from total meters.

Light-fixture openings (reserved)

Mark recessed-light positions and the BOM annotates board cuts so you don't over-cut.

Auto-generated outputs

Six artifacts at once — print A4 and bring it to the shop or hand it to the client.

🪵

Batten BOM

Main and sub batten meters & counts, with 12-ft / 8-ft stock cut plans laid out.

📦

Board layout drawing

Compare 4×8 vs 3×6, see which wastes less; 2D layout with auto-numbered panels.

🔗

Hanger spread table

Hangers auto-laid from room dimensions, spacing within 60–90 cm.

🎛️

3D 8-layer breakdown

Slab / hangers / main battens / sub battens / boards / joints — toggle each.

🧾

A4 quote

Client info + line items + totals + terms on one A4 page. Save as PDF from your browser.

📊

BOM CSV export

Excel opens cleanly, crews use it for procurement directly.

Real outputs

These are actual artifacts the tool produces — they update live as you change dimensions.

2D plan + main/sub batten grid
Drag room dimensions, framing lays out automatically, seams always land on batten centers.

3D structure with 8 toggleable layers
Slab / hangers / main / sub / boards / joints — clients grasp install order in seconds.

Cut plan + BOM
How each 12-ft batten gets cut, with offcut sizes — hand it to the lumber yard and they cut accordingly.

※ Change dimensions / switch board specs / change batten spacing — these all redraw live.

Who it's for

🔨

Carpenters / drywall installers

Client asks 'how much for a living room ceiling per ping' — pull out your phone, change dimensions, quote re-issues instantly.

🪜

GCs / interior designers

Put a 3D view + quote in one proposal, client closes on the spot. Spec changes don't require a redraw.

🏠

DIY wood ceiling builders

Draw the room → tool tells you to order N 12-ft battens, M fiber-cement boards. Walk into the lumber yard ready.

🎓

Carpentry academy students

Run the framing logic from class on real numbers. Bridge from practice to client work seamlessly.

⚠️ Not for these situations

Steel-stud / drywall systems — this tool computes wood framing, not T-bar steel
Non-orthogonal rooms (slanted walls, curves, multiple bays) — v1 supports rectangle, L, and small bay extrusions
Precise positioning of HVAC vents / light openings — this tool sizes framing and boards, not openings
Existing CAD/Revit workflows — this fills the gap for those who lack CAD but still need takeoffs

When you'll use it

🔨 On-site quoting

Client asks 'how much for the living room ceiling per ping' — pull out your phone, criss-cross framing + board layout + hangers, A4 quote in 30 seconds, close right there.

🪜 GC / designer pitch

Pitch ceiling, floor, raised platform together: 3D + quote on one sheet, clients read drawings 10× faster than Excel — no overnight grind.

🏠 DIY home renovation

Tearing down an old drop ceiling, rebuilding wood framing: draw the room → tool tells you how many 12-ft battens and fiber-cement boards to order. Skip asking the contractor.

🎓 Carpentry academy student

The framing logic and seam-alignment principles you learned in class — this tool lets you see how the algorithm computes them. Bridge from practice to client work.

FAQ

How does wood ceiling framing differ from steel-stud T-bar?▾

Wood framing uses 'batten grid + fiber-cement boards' — 12-ft battens with boards screwed on, supports light fixtures, allows shaping. Steel T-bar uses T-bars + mineral fiber tiles, modular and easy to dismantle but weak load and hard to shape. This tool calculates wood framing.

Should I order 4×8 or 3×6 boards?▾

4×8 (122×244 cm) is the most common in Taiwan — large sheet, good for big living/dining rooms. 3×6 (91×183 cm) is smaller, less waste in small spaces, easier to transport. This tool toggles both specs and compares waste automatically.

Do seams really auto-align with battens?▾

Yes. The system back-solves main batten spacing as 'board short edge ÷ N', so board seams always land on batten centerlines — edges always supported, no year-end cracks. Switch board spec (4×8 / 3×6) and batten spacing auto-updates.

Can I export PDF / CSV?▾

A4 quotes print straight from the browser → Save as PDF. Logo / company info / terms are filled once in 'Branding' panel and reused. BOM exports to CSV, Excel opens cleanly.

How much does the tool cost?▾

Pro Monthly $9/mo — includes all 26 furniture templates + ceiling framing + floor simulator + raised platform. Pro Annual $79/yr — adds client quoting system + STL/CNC export + unlimited dimensions.

Can I buy just this tool?▾

Yes. Find the single-tool unlock for ceiling on /pricing. But Personal covers all 26 furniture + 3 interior tools — most people end up subscribing to Personal instead.

What about my bay window or slanted wall?▾

v1 supports rectangle, L, and small bay extrusions. Non-orthogonal (slanted walls, curves) are on the roadmap, with seamless upgrade.

Will the tool keep getting updates?▾

Yes. 3D layer toggles, board layout, joint emphasis — all added incrementally after launch. Roadmap: multi-fixture/vent openings, auto load calc, RC slab field data integration.
