Pick a tile layout, enter the tile size and grout joint, and get a hatch pattern file for Revit or AutoCAD. The preview is drawn by reading the generated .pat text back, so it shows exactly what the file contains.
Export saves a .zip containing the .pat file, because the viewer can't save .pat files directly. Unzip it, then in Revit go to Manage › Additional Settings › Fill Patterns › New › Custom › Import.
Every pattern line is angle, x, y, shift, offset, dash, space. It draws one tile edge, then repeats it: offset is the distance to the next parallel copy, shift slides that copy along the line, and the dash/space pair draws the edge and skips to where the same edge comes round again.
Each tile in the repeating cell contributes four lines (bottom, top, left, right). The builder works out the repeat cell for the layout, then for each edge finds the shortest distance before that edge repeats along its own line and the matching offset to the next line. That is the same arithmetic the CADhatch spreadsheet does with hand-written formulas, generalised so it works for herringbone, basketweave and rotated layouts too.
| Layout | Lines | Notes |
|---|---|---|
| Stacked | 4 | Tiles aligned in rows and columns. |
| Running bond | 4 | Each course moves the offset again (⅓ bond goes 0, ⅓, ⅔). |
| Alternating | 8 | Every other course shifts. This is the spreadsheet's staggered column. |
| Herringbone | 8 | Long side is fitted to whole widths (2:1, 3:1…) unless you untick the option; other ratios give very long repeats. |
| Basketweave | 8 × tiles per block | Tile height is adjusted so a block of tiles makes a square. |
| Hopscotch | 8 | Large and small square, fitted the same way. |
The pattern lines are the same in both. Revit adds a few header lines AutoCAD ignores:
;%UNITS=MM or INCH sets the units of every number in the file.;%VERSION=3.0 is the file format version.;%TYPE=MODEL makes it a model pattern, sized in real millimetres, which is what you want for tiles. DRAFTING patterns keep the same printed size at any view scale.AutoCAD reads the *name,description line only, and the file name must match the pattern name.
