Yes, but with significant limitations.
Verdict: The free methods are educational but frustrating for real projects. The $99-$199 for HatchKit pays for itself in the first hour.
You cannot "convert" a DWG to a PAT file for the same reason you cannot convert a novel into a single letter of the alphabet. A DWG contains millions of coordinates; a PAT file contains one repeating unit (a tile). convert dwg to pat file
Conversion actually means: Extracting a small, tileable geometry from your DWG and writing a mathematical definition that repeats it.
If you do not want to mess with scripts, several websites can convert a DXF (which you export from your DWG) into a PAT file. Yes, but with significant limitations
Step-by-Step:
If you want, tell me which CAD program you have (AutoCAD, BricsCAD, DraftSight, FreeCAD) and I’ll give step-by-step commands or a small example .pat file you can copy. Verdict: The free methods are educational but frustrating

There are several tools available that can help you convert DWG to PAT. Here are a few options:
If you want to convert DWG to PAT file successfully in under 10 minutes, follow this flowchart:
If you cannot afford software and your pattern is purely orthogonal (straight lines at 0°, 90°, 45°), you can manually write a PAT file.
