Truss Builder

About this app

Truss Builder turns a simple building idea into a clear, quote-ready roof truss package — right from your phone.

Size a shop, garage, barn, or house and watch the roof framing come together in live 3D. Every truss updates as you change span, length, wall height, pitch, heel, and overhangs, so you can see exactly what you are asking for before you send it in.

THREE WAYS TO START
• Rectangle building — enter span, run, and wall height, then pick truss shape, roof and ceiling pitch, heel height, eave details, cut preference, and drop gables.
• Draw a building — trace exterior walls with Up / Down / Left / Right and feet to model L-shapes and wings, with a live plan sketch and 3D wings.
• I have plans — upload plan PDFs or images and we will try to build an approximate 3D model from them for you to review.

HAND-DRAWN FOUNDATION (APP ONLY)
Sketched your foundation on paper? Snap a photo, tap the corners, enter one known wall length, and Truss Builder scales the outline and drops it straight into the 3D builder. The photo is processed on your device.

3D TRUSS VISUALIZATION
• Orbit, zoom, and tap the roof to edit
• Heel and truss side views with estimated truss counts
• Download 3D views as images for your records or your crew

SAVED BUILDS
Create an optional free account to save builds to the cloud, reorder them, open them on any device, and download a side-by-side compare sheet. No account is needed to build or request a quote.

SHARE LINKS
Send a read-only link to a customer, lender, or crew. Anyone with the link can view the 3D building and specs — no login required.

QUOTES FROM SBCA-APPROVED PLANTS
When you are ready, send your build in for a quote and truss design. A truss specialist reviews your package and works with SBCA-approved truss manufacturers in your area to prepare pricing and an engineered truss design.

BUILT FOR REAL JOBSITES
Truss Builder is made for builders, contractors, and homeowners. It helps you capture the right specs — it does not invent snow loads, pricing, or delivery dates. Loads, sealed engineering, pricing, and delivery are always confirmed by a specialist and the manufacturing partner.
