Using autocad hatch patterns
Individual PAT filenames match their pattern names. The combined architectural-metric.pat contains all fifteen definitions. Values are millimetres: start with HPSCALE=1 in an mm drawing, or 0.001 in a metre drawing. Running bond and stretcher are the same bond family with different module dimensions. Curved-looking insulation and growth rings use short straight segments, as required by PAT line syntax.
- AutoCAD: put the standalone PAT files in a folder listed under Options → Files → Support File Search Path, then reopen the hatch selector and choose the custom pattern name.
- Alternatively append the combined definitions to a backup copy of acadiso.pat. Do not overwrite the original installation file. Keep the trailing blank line and avoid duplicate pattern names.
- Apply the hatch, choose scale 1 for mm, and inspect spacing using a known module: the square tile grid is 100 × 100 mm. Adjust hatch origin, rotation and lineweight to the drawing.
- Revit: Manage → Additional Settings → Fill Patterns → New → Custom → Import a PAT. Select the pattern and verify import scale. For a model pattern, work on a copy with ;%UNITS=MM before the definition and ;%TYPE=MODEL immediately after its *NAME header. Drafting patterns instead describe sheet-scale graphics.
- These are AutoCAD-first PATs, not pre-certified Revit fill patterns. Complex motifs can exceed a Revit version's import limits: try the simple square tile first, simplify a copy if needed, and verify spacing before assigning a material.
AutoCAD, Revit and presentation software
AutoCAD
Open DXF directly; no DWG conversion is required. Check INSUNITS=4 and insert named annotation blocks into a millimetre paper-space layout at scale 1. Use EATTEDIT for populated attributes, BEDIT for block geometry, and Save As if you need DWG. Custom hatch installation is explained on the PAT download page.
Revit
Use Insert → Import CAD in a drafting/detail view with import units explicitly set to millimetres for a 2D reference. Imported CAD attributes do not become native labels or sheet parameters; build a native annotation family for automatic references. PATs use Manage → Additional Settings → Fill Patterns → New → Custom → Import; verify units, model/drafting type and compatibility as described in the hatch guide.
ArchiCAD
Use the DXF/DWG translator with millimetre units and merge the 2D DXF into a worksheet/detail as a reference. Imported CAD is not a native GDL object or automatic marker. Recreate native fills or reference labels when needed; AutoCAD PAT files do not directly become ArchiCAD fills.
SketchUp and LayOut
In SketchUp editions that support DXF import, set units to millimetres and confirm the imported size. For LayOut boards, place transparent PNGs as images and set an explicit paper width; PNG pixel count alone does not calibrate a scale bar. PDF/SVG placement support varies by version and platform. Prefer a supported vector route for print, and measure the final output at 100%.
Illustrator and InDesign
Open SVG in Illustrator to edit shapes and live text; install DejaVu Sans or substitute your office font. In InDesign, place the SVG/PDF at 100% and avoid fitting content to an arbitrary frame. For dark boards choose the white PNG. PAT files are hatch instructions, not placeable artwork: use their PNG swatch or open the DXF in a compatible vector workflow.

Frequently asked questions
Do the PAT files install directly in every design application?
No. AutoCAD uses PAT definitions directly, while Revit imports compatible custom fill patterns with its own units, pattern type and complexity limits. ArchiCAD and SketchUp LayOut do not directly share AutoCAD's PAT system. Use the DXF as a reference or the supplied swatch image, or rebuild a native fill.
Are these files free for commercial use?
Yes. These original generated symbols are released under CC0 1.0 Universal. Personal and commercial use, editing and redistribution are allowed without attribution. They are supplied as-is; check your project's conventions before issuing construction drawings.
Are the CAD files DWG or DXF?
The CAD downloads are AutoCAD R2013 DXF, not DWG. AutoCAD opens DXF directly and can save it as DWG. Geometry is in millimetres, with INSUNITS=4; annotation blocks use A-ANNO-SYMB. SVG and PDF are vector files, while PNG and WebP are display images.
How do I keep the print scale correct?
Place SVG/PDF at 100% / actual size, use the matching paper dimensions and disable fit-to-page. Insert paper-mm CAD annotations at unit scale in a millimetre layout. PNG pixel dimensions alone do not establish a calibrated print size. Always measure a known bar or sheet dimension.
