Bookshelf — how it works

1 · Sketch. Draw the shelf as a line drawing on an inch grid. Each line is the centerline of a board seen from the front: a horizontal line is a shelf, a vertical line is a side or divider. Lines snap to the grid and to other lines, so shelves land exactly on the sides.

2 · Build. Pick each line and choose its wood: stock (1×12, ¾" plywood, …), thickness, board width (the depth of the shelf). Joints are worked out automatically where lines meet: at a corner one board runs over the other, a shelf butts into a side, a divider that crosses a shelf is cut into pieces. Click a joint marker (or use the list in the side panel) to change it — butt, dado, rabbet, miter, or which board runs through. The cut list then notes the dado or rabbet on the board that gets cut, with its position.

3 · Cut list. Every piece with its final cut length, grouped by identical size, plus a stock plan: how many boards or sheets to buy and a cutting diagram for each.
