Pattern generators · 12 tools
Islamic geometry, jali lattices, honeycomb, hexagon, diamond, grid, mandala and rosette patterns generated at the panel size with cuttable bar widths.
Geometric pattern is the most requested and most mis-cut category in decorative work. A star-and-polygon Islamic pattern drawn by hand has hundreds of tiny overlapping segments; scaled to a 600 mm screen it produces bars of random width, some too thin to survive, and a file the laser takes an hour to cut because every segment is a separate line.
The generators build patterns from their geometry: a tile, a symmetry, a repeat count and a bar width, welded into one closed sheet with a frame. Change the panel size and the pattern re-tiles; change the bar width and every bar changes together. The output is a single cuttable shape, ready for the laser, router or plotter, or for the stencil and nesting tools.

Eight-point star lattice panels.
Islamic Pattern and Islamic Geometric Pattern Generators cover the classic star systems (6-, 8-, 10- and 12-point); Jali Pattern Generator does screen lattices; Honeycomb, Hexagon, Diamond, Triangle and Grid cover the regular tilings; Mandala and Rosette build radial designs; Decorative Border frames a piece.
Enter the finished width and height in millimetres and the number of repeats across. The generator scales the tile so whole repeats fit and the pattern closes at the frame.
Bar width is the material left between openings; frame width is the solid border. Both follow the structural rules below and the preview shows the thinnest bar.
SVG or DXF as one welded shape. Send it to Stencil Maker for a paint stencil, to the boolean tools to combine with lettering, or to nesting for a batch of panels.
Vinyl: 3 mm minimum or the bars lift. 3 mm acrylic or MDF: 4 mm bars. 6 mm MDF free-standing screen: 10 to 12 mm bars. Paper and card for lampshades: 2 mm is fine.
Eightfold patterns (the khatam) tile on a square grid and suit square panels; sixfold and twelvefold tile on hexagons and suit long screens; tenfold patterns need a wider repeat and read best above 400 mm.
For a jali the ratio of open area to bar area sets the light and privacy; 40 to 50 percent open is typical for a window screen, 25 to 35 percent for a privacy partition. The generator reports the open percentage.
Radial patterns cut cleanly when every ring connects to the next; the generator enforces connection so the finished piece is one part, not a set of rings.
They are built from the classical constructions: the eight-point star from a square grid, six- and twelve-point from a hexagonal grid, with the traditional interlace proportions. Adjust the star angle and bar width to match a specific historical example.
Yes. Generate the pattern, then use the boolean Difference tool with a calligraphy composition to knock the text out of the lattice, or place the text on a plain panel inside a patterned border.
Honeycomb, hexagon and small-repeat Islamic patterns throw the cleanest shadows. Keep bars at 2 to 3 mm on card or 3 mm on thin MDF, and add a 15 mm frame for gluing.
Decorative Border Generator produces a strip of a set length with a repeating motif and end caps; Repeating Pattern Generator does the same for area fills on glass film.
