If you are a casual user who just needs a one-off custom texture for a specific rendering, stick with AutoCAD’s built-in feature.

Copy your new .pat file and paste it into the AutoCAD Support folder. dwg to pat converter
Unlike standard vector drawings, a PAT file does not just store shapes; it stores mathematical instructions. These instructions tell the CAD software: The precise angle of each line. The X and Y coordinates where the line starts. The displacement and offset rules for repeating the line. The dash-dot sequence for broken lines.
Draw one wooden plank with end grooves at (0,0). Use the converter to generate the base. Then, manually edit the PAT file to add a second offset row (common practice for herringbone patterns). If you are a casual user who just
A more powerful built-in method is available in recent versions of AutoCAD (like 2024 and later). Commands such as DRAWHATCH and SAVEHATCH allow you to draw a pattern using simple entities (lines, arcs, etc.) within a defined 1x1 unit boundary. The DRAWHATCH command provides the framework to define the pattern, and SAVEHATCH then writes that definition to a PAT file. This is an excellent method for creating precise, measured patterns directly from draft geometry.
In the Hatch creation ribbon, open the pattern drop-down menu and change the type to Custom . Unlike standard vector drawings, a PAT file does
