Save material on any cutter: pack SVG and DXF parts onto sheets of plywood, acrylic, metal, vinyl or card for laser, vinyl, CNC and plasma cutting. Everything runs in your browser; your files are never uploaded.

- True shape interlocks parts by their actual outlines and rotates them so objects tuck into each other's gaps.
- Bounding box packs rectangles fast.
Order walk (the default) keeps changing the order parts are placed in and lets each part take its best angle. Genetic breeds layouts from the best ones found, with each part's angle fixed, so it tries many more layouts; it usually finds better layouts with fine rotation steps and large jobs, but can do slightly worse at 90°.
Extra background workers try more layouts at once, so a search usually tries more layouts in the same time; how much depends on the method.
Each extra worker uses more memory, about 100 MB on a job of 120 parts. On a lower-spec computer (little memory or few processor cores), leave Workers off.
Width of material the cut removes (beam, blade or bit). Added to the spacing between parts so neighboring cuts never overlap.
Moves closed cut paths by half the kerf (outlines out, holes in) in the downloaded files, so parts come out at their drawn size. Filled areas and open lines stay as drawn.
- Turn off kerf offset in your cutter's software. The downloaded files already include it, so leaving it on applies the kerf twice: parts come out a full kerf too big and holes a full kerf too small.
- Measure the kerf for this material and these settings; a wrong kerf makes every part the wrong size.
- Compensated curves are written as fine straight segments, so circles are no longer true arcs in a DXF.
- Files downloaded with compensation are marked. If you add one here again, it is not compensated a second time.
Measure it from a test cut
Cut a square with Compensate kerf on objects off and no kerf offset in your cutter's software, then measure the piece that drops out.

Parts
Sample partsThe padlock button on each part sets how it may turn; each click moves to the next setting. Free (open padlock): turns at the Rotation step. Grain (wavy lines): only 0° or 180°, so the grain of wood or brushed metal runs the same way on every copy; in Bounding box it doesn't turn. Locked (closed padlock): never turns.
The frame button on a part with holes lets other parts nest inside them; turn it on only if every closed inner outline is cut, not scored. A frame crossed by a diagonal line marks a part with no holes to nest in.
