Every tool solves the arrangement, draws it to scale, and prints as a working document you can take to the bench. Saw kerf is subtracted at every cut, grain direction is respected, and joints land where they can actually be supported.
Real output: 22 parts nested on a 2440 × 1220 sheet, kerf included.
Not a number in a box. A dimensioned drawing you can print, fold into your pocket and work from — plus the cut list that goes with it.
Every riser dimensioned, the angle, and the dropped-stringer correction applied.
Pin width adjusted so the spacing divides exactly — printed at 1:1.
Parts placed, offcuts shown, kerf subtracted at every cut line.
Plywood, MDF, bar stock and trim — every part out of the fewest sheets.
Stairs, roofs, walls and decks. The geometry, drawn and dimensioned.
Tile, concrete, gravel and paint — quantities you can actually order.
Layouts that divide evenly, with templates you print at full size.
Yes, and there is nothing to sign up for. The tools run entirely in your browser, so there is no server cost per user and no reason to put anything behind a login.
No. Nothing is uploaded, nothing is saved, and there is no tracking. Close the tab and it is gone — which also means write your numbers down if you need them again.
Both, on every tool. The unit selector converts the whole form, and the drawings and cut lists follow.
No. These are planning aids. Span tables, building regulations and a qualified opinion are what structural decisions need — the geometry here is a starting point, not a sign-off.
