Native PAT files have limitations. They typically only support straight lines. However, modern CAD versions support "Custom PAT" files that can handle curves and complex geometries—provided the conversion is done correctly. Imagine you have drawn a complex interlocking brick pattern, a unique herringbone wood floor, or a custom security grating in DWG format. You want to apply this design as a hatch across a large area in another drawing. Manually copying and pasting the geometry would crash your software due to file size.

PAT files operate on a "seed" concept. The converter analyzes a bounded area of your DWG, identifies the vectors within that bounding box, and writes a script that repeats that block infinitely. If your DWG contains overlapping lines, open polylines, or tiny gaps, the PAT definition will fail inside AutoCAD (resulting in a "Hatch pattern not valid" error).
