If you don't strictly need a .pat file and just want to use a block or image as a hatch, use the in full AutoCAD. Block to PAT — AutoCAD Pattern Conversion #AutoCAD #Tips
Before investing time in conversion, ensure you actually need a PAT file. Common use cases include:
A PAT file, also known as a Pattern file, is a text-based file format used in various CAD software, including AutoCAD. PAT files contain a set of data that defines a pattern or a hatch, which is used to fill a closed shape or a region in a CAD design. PAT files are often used in architectural and engineering designs to add textures, materials, or other visual effects to a drawing.
Converting DWG to PAT is necessary when you want to use a DWG file as a pattern in a CAD software that only supports PAT files. Here are some common scenarios where you might need to convert DWG to PAT: convert dwg to pat file
: Utilities like GETPAT or PatOut are specifically designed for this.
The fastest way to use DWG geometry as a hatch without leaving AutoCAD is the SuperHatch command. While it does not create a standalone PAT file, it achieves the exact same visual result. Step-by-Step Execution
The short answer is: Unlike converting a JPG to a PNG, a DWG (a full drawing database) and a PAT (a text-based pattern definition) are fundamentally different. However, you can extract a design from your DWG and define it as a custom hatch pattern. If you don't strictly need a
: A professional-grade standalone editor that can import DXF/DWG and export a formatted .pat file.
: Ensure your pattern is made ONLY of lines or polylines. Arcs, circles, and splines are generally not supported in standard PAT files.
If you have AutoCAD installed on your computer, you can follow these steps to convert your DWG file to a PAT file: PAT files contain a set of data that

Once you have successfully generated your PAT file, you need to add it to AutoCAD to verify its appearance. Copy your new .pat file.
Use the DXFOUT command and save the file as a to ensure maximum compatibility.
