Your DWG pattern scale is too small. Scale up your geometry in the DWG file before running it through the online converter.
A PAT file only understands lines, not blocks, splines, or circles.

Are you trying to create a pattern for a specific industry (e.g., masonry, stonework, paving)?
Slowly, pixel by pixel, the grey block began to fill. Lines appeared—jagged, irregular, dark grey and lighter silver. The math that would have taken Elias weeks to calculate had been done in seconds by the algorithm in the cloud.
The converter calculates the vector displacement for each line segment (dX, dY, angle). It writes these calculations into a structured text file with the .pat extension. The output is a hatch pattern that AutoCAD can read instantly. Your DWG pattern scale is too small
Use the HATCH command, select "Custom" from the pattern type, and your new pattern will appear in the list. Tips for Success and Troubleshooting
Ensure all lines are perfectly connected if necessary, or purposely disjointed if you want a custom, non-continuous pattern.
While fully automated, cloud-based web converters for this specific CAD-to-code translation are rare due to the complexity of vector tiling, several highly efficient online resources, scripts, and freeware tools make this process seamless. 1.

Express Tools like SUPERHATCH allow image or block-based fills within AutoCAD.
Before diving into the conversion methods, it's crucial to understand the fundamental difference between the two file types.
A PAT file (Pattern File) is an ASCII text file that defines hatch patterns for AutoCAD and other CAD software. Unlike image-based patterns (JPEG or PNG), PAT files are vector-based and scale infinitely. They define a "tile" or "unit" that repeats infinitely in the X and Y axes.
Several third-party applications and web-based generators allow you to map out your patterns visually.
