Dwg To Pat Converter File
Completely free; works entirely within the AutoCAD command line.
Manually coding a complex parquet floor or stone masonry pattern can take days. A converter does it in seconds.
It is best practice to draw your repeating tile within a standard grid size—often or the actual real-world dimensions (e.g., drawing a 200mm x 100mm brick tile at a 1:1 scale). Ensure your start and end points align perfectly so the pattern snaps together seamlessly when tiled. Step 4: Run the Converter dwg to pat converter
A .pat file is a plain text file that contains the code required by AutoCAD and other CAD software (like BricsCAD or Revit) to render hatch patterns.
Several specialized tools and utilities are commonly used by professionals to handle this conversion: Completely free; works entirely within the AutoCAD command
If you do not have a full version of AutoCAD (for example, if you use AutoCAD LT, which doesn't support LISP routines or Express Tools), you can use standalone converter programs. Software like or specialized online conversion portals let you upload a clean DXF/DWG file of your pattern tile and download the compiled PAT text file. Step-by-Step: How to Prepare Your DWG for Conversion
(Example: *MyPattern, 0, 0, 0, 0, .5, .5,-.5 … enough said.) It is best practice to draw your repeating
A plain-text file containing code that defines a hatch pattern. The code specifies the angles, start points, offsets, and dash-dot sequences of lines.
If you want to convert a specific block or geometry into a pattern without external software, follow these steps:
