Woodworking Designs

Lay out parts in 3D, hang a door that actually swings, and get a cut list you can trust.

Built for how wood actually goes together

Design parts to actual stock dimensions, test joint clearances, and catch alignment mistakes before making the first saw cut.

Hinge physics

Doors that swing on real hinges

Hang a door on real hinges and play the swing. If it catches on the carcass or face frame, you find out in 3D, not at the saw table.

A cabinet being assembled in 3D, each face labelled Top, Door, Back, Left Side, Right Side and Bottom as a part is carried towards it.
Face snapping

Parts that snap flush

Carry a board towards another and pick the face it lands on while it is still in your hand. No manual coordinate math required.

Commercial board cutting diagrams

Every part placed on a real commercial board length, with the offcut measured so you know whether it is worth keeping for your next project.

Start from a template, or from a bare board

Five starting points, and each one is a model rather than a picture of one: a table, a chair, a frame and panel door, a cabinet, and a cabinet whose door is already on its hinges. They open with every part cut to size and named, and every one of those sizes is yours to change.

Or open an empty plan and add boards one at a time. A template is a head start, not a track you have to stay on.

Dining Table 9 pieces · 1240 × 640 × 725 mm
Side Chair 6 pieces · 400 × 400 × 750 mm
Frame and Panel Door 5 pieces · 500 × 19 × 700 mm
Cabinet Carcass 6 pieces · 600 × 400 × 800 mm
Cabinet (Hinged Door) 6 pieces · with working hinges
The Insert sheet on the Furniture tab, showing five templates as cards: Table, 9 pieces, 1240 by 640 by 725 millimetres; Chair, 6 pieces; Door (Frame and Panel), 5 pieces; Cabinet, 6 pieces; and Cabinet (Hinged Door), 6 pieces, hinged.
Every template says how many pieces it is and how big it comes out, before you pick it.

Numbers you can take to the yard

The cut list for a dining table: tabletop in pine at 124 by 64 by 2.5 centimetres, four legs and four aprons in spruce, each with its finished size.
Cut list generated directly from the 3D model with exact part sizes and total wood volume.

The cut list comes straight from your 3D model, so it always matches what you drew. Every part shows its wood and its finished size, with the total amount of wood at the top.

The buy list goes one step further: it works out which boards to buy, in the sizes the shop actually sells, then shows you which parts to cut from each board.

What is free, and what is not

No subscription. Planning a build is bursty, and charging monthly would cost the most in the months you use it least.

What the buy list actually does

The cut list says what your parts measure. The buy list goes one step further and works out which boards to put in the trolley, in the lengths the shop stocks, then tells you how much of each one you will use and how much is offcut.

Store mode: readable one-handed in the aisle

Built for hands holding lumber

Store mode takes everything else off the screen. In the lumber aisle, your hands are full of stock; tick boxes are oversized so you can check off 8-foot and 12-foot boards with your thumb as you load the cart.

Store mode: two rows filling the width of the screen, 2x4 Pine 8 foot times one and 2x4 Pine 12 foot times one, each with a large empty tick box.
High-contrast aisle checklist with generous touch targets for loading one-handed.
