Random flagstone (large) pattern — free hatch (.pat), texture & 3D tiles

Random flagstone (large) is a stone layout built from 196 tiles per repeat (sizes 820.7 × 683, 919.6 × 725.6, 1016.9 × 933.7 mm (+193)), repeating on the lattice a = (9800, 0) mm, b = (0, 9800) mm, a cell of 96040000 mm². The seamless texture repeat is 9800 × 9800 mm. Download it as a CAD hatch, a seamless texture or SVG and DXF lines, count the tiles for your room, or build it as real 3D tiles in SketchUp. All free.

The PAT files are approximate: this pattern has edges that a PAT line family cannot draw exactly, so they are drawn as stepped lines. SVG and DXF are exact.

Hatch units are millimetres at the default tile size. For other sizes use the hatch page or the editor, which exports every format at the size you set.

Enter the room, grout and tile size. The count comes from the same engine that lays the 3D tiles, so the cut tiles are real cuts against your room edges (a 4 × 3 m room is shown first). More patterns: tile calculator.

Questions about Random flagstone (large)

How many Random flagstone (large) tiles do I need for a 4 × 3 m room?

With the default tile size and a 3 mm joint, a 4 × 3 m floor needs 15 full tiles and 23 cut tiles (38 whole tiles counting each cut tile as one). The net area is 12 m² and the tiles bought cover 17.79 m², so cutting alone wastes 48.3 %. Enter your own room and tile size in the calculator on this page.

Is the Random flagstone (large) hatch exact?

Not entirely. A PAT file can only hold straight dashed line families, and Random flagstone (large) has edges that no such family reproduces exactly. The file draws 1176 edges as a staircase of horizontal and vertical steps of 490 mm, within a fraction of a step of the true edge. The SVG and DXF downloads are exact.

How do I use the .pat file in AutoCAD?

Copy the .pat file into a folder that is in AutoCAD's Support File Search Path (Options > Files), keep the file name (the pattern name inside the file matches it), then pick the pattern in the HATCH command. If Windows blocks the download, right-click the file, open Properties and tick Unblock.

How do I use the .pat file in Revit?

In Revit open Manage > Additional Settings > Fill Patterns, click New, choose Custom and browse to the .pat file. Use the model variant when the pattern must keep its real size on the building.

What is the repeat size of Random flagstone (large)?

One repeat of the lattice covers 96040000 mm² with 196 tiles. The smallest rectangle that repeats seamlessly in both directions, which is what a texture image needs, is 9800 × 9800 mm at the default sizes.
