Opus Romano (three sizes) pattern — free hatch (.pat), texture & 3D tiles

Opus Romano (three sizes) is a stone layout built from 3 tiles per repeat (sizes 600 × 600, 600 × 400, 400 × 400 mm), repeating on the lattice a = (1000, -400) mm, b = (400, 600) mm, a cell of 760000 mm². The seamless texture repeat is 3800 × 3800 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.

Questions about Opus Romano (three sizes)

How many Opus Romano (three sizes) 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 39 full tiles and 17 cut tiles (56 whole tiles counting each cut tile as one). The net area is 12 m² and the tiles bought cover 14.28 m², so cutting alone wastes 19 %. Enter your own room and tile size in the calculator on this page.

Is the Opus Romano (three sizes) hatch exact?

Yes. The .pat file draws the tile edges exactly: every edge direction of this pattern is parallel to a lattice vector, so a PAT line family reproduces it without approximation. Units are millimetres and the pattern name inside the file is opus-romano-three-size.

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 Opus Romano (three sizes)?

One repeat of the lattice covers 760000 mm² with 3 tiles. The smallest rectangle that repeats seamlessly in both directions, which is what a texture image needs, is 3800 × 3800 mm at the default sizes.
