Calculated materials & cut lists
Rules-based & repeatable
Real 3D you can orbit
From idea to build day
Three steps, no jargon
You describe the project. BudDIY does the math and draws the model.
Describe your project
Pick a type and enter a few dimensions — an 8×10 shed, a 12×16 deck. Plain choices, no engineering degree required.
See it in 3D
BudDIY builds a project-specific 3D model as you go. Orbit it, and switch between the finished look, the framing, and an x-ray view.
Choose your build sheets
When you're ready, generate a saved assembly manual for one project or unlock supported projects with Pro.
What's inside
From a rough idea to a clear planning draft
Rules-based calculations keep the model, materials, cuts, and instructions working from the same project details.
Calculated 3D
See it before you build it
Orbit a calculated 3D model of your build. Flip between the finished exterior, the framing, and an x-ray view to understand how the pieces fit.
- Exterior, framing & x-ray modes
- Pinch to zoom, drag to orbit
- Built-in geometry and component checks
Materials & cut lists
Materials and cuts, organized
BudDIY turns your dimensions into a calculated shopping list and a step-by-step cut list — board by board, in build order. The same inputs follow the same rules every time.
- Shopping list with quantities
- Ordered cut list & assembly steps
- Save, revisit & share designs
Your Garage
Keep track of the tools you own — organized by category, with condition notes and a reminder of what you've lent out. Know what you've already got before your next project.
Shopping list
A running materials & tools list you can check off at the store, with a running total. Send a build's materials straight to it, or add your own items any time.
Build at your pace
Design for free. Pay when you need the sheets.
Explore the full design loop first, then choose one project or account-wide build-sheet access.
