How to convert a DWG (AutoCAD) file to a PAT (Hatch pattern) file

Why use this?

It’s the fastest way to "recover" a custom pattern if the original source file was lost. 2. Creating New Patterns from Blocks (SuperHatch)

Step-by-Step Guide to Converting DWG to PAT Files

1. Clean the DWG: Delete all text, dimensions, and non-pattern geometry. Keep only 1 tile of the repeating pattern.
2. Trim to Boundaries: Use BOUNDARY or TRIM to ensure lines stop exactly at the tile edge (e.g., a 1x1 unit square).
3. Use SuperHatch (Indirect): While AutoCAD doesn't export DWG→PAT natively, you can use _SUPERHATCH to tile the DWG block, but for exporting, use Method B.
