Customise and snap together
Resize boards, rotate them, drag them around — they snap face-to-face and corner-to-corner automatically. Combine templates to design exactly what fits your space.
Get your cut list instantly
A clean, sorted cut list generates as you build. Copy it to your phone or export as CSV — ready for the timber yard.
