Draw a shape with L line, C curve, R rectangle or O circle, or start from a template.
Lines, curves (hold Shift to bend inward), rectangles and circles, all in real millimetres. Double-click a shape to edit its points.
Select a shape and press Add seam + stitching. Right-click holes to select ranges, delete, re-space or move them.
Ctrl+P makes a true-size PDF. Print at 100% and check the 100 mm ruler before cutting leather.

Auto (default): a magnifier appears while you draw or move points at 100% zoom or less. Z turns it off and back on; the Loupe button picks Auto / On / Off; Alt+wheel or the 2×–8× menu sets magnification.
T, click to place a note in real millimetres; double-click to edit. Notes print and export with the pattern.
Select a closed shape → Add seam + stitching. The seam zone is a band inside the cut edge (default 10 mm); holes sit on the stitch line, centred in it. Change pitch, hole size and shape in the Stitch card. Sharp corners get a hole exactly on the corner.
Right-click a hole → Assign Start, right-click another → Assign End. Then delete, re-space or move only that range. Drag any hole to place it by hand. Red rings mean holes are too close to each other or to the edge.
Ctrl+P → Download PDF. Print at 100% / Actual size with "Fit to page" off. Measure the 100 mm ruler and the 50 mm square on the cover page before cutting. Large pieces are split over pages: trim one edge of the grey overlap, line up the crosses, tape.
The Pages bar puts paper sheets (A4, Letter…) on the canvas. Drag them over your pieces, then print with Use my sheets (exactly those pages) or Auto-tile (split over as many pages as needed).
Pick the project material (leather, canvas, fabric) on the start card. Each piece can differ: set it in Pattern Tools or right-click → Material. Pieces are tinted by material; the Materials tab and 3D preview switch to leather or woven cloth.
Seam allowance, mirror / cut as pair, marks (notches, match points, drill holes), grain and fold lines, seam match (compare two edges) and a material estimate (sq ft of leather, metres of cloth).
Seam & Stitch panel: switch off edges that stay open (pocket mouths), choose hand (punched holes) or machine (dashed line), and Align holes with… another piece so stacked layers are punched in the same place.
Export PDF (true size), SVG, Laser SVG (cut / score / engrave layers) and DXF for CAD or cutters. Import SVG / DXF brings outlines in at their real size.
