Does not create a true, reusable .PAT text file; can bloat file sizes significantly. Type: Standalone Professional Software
As experts on the Autodesk forums note, it's simply "not as simple as you think". This article cuts through the noise to provide a definitive guide on the best tools, methods, and workflows to achieve this effectively. For a long and authoritative piece, we'll explore everything from the reasons to convert, to a detailed comparison of the top solutions like HGEN, PatOut, HatchKit, and more.
A designer wanting to create a realistic wood grain pattern can draw the organic lines in AutoCAD and use SuperHatch. However, to get that pattern into Revit for a family, they can use HatchKit to export it directly to .PAT . As one user noted, they made "this very custom wood grain hatch pattern that I eventually want to import into revit".

The Ultimate Guide to Finding a Better DWG to PAT Converter CAD designers and architects frequently need to convert AutoCAD drawing files (.DWG) into hatch pattern files (.PAT). Standard CAD software rarely includes an efficient, built-in way to export custom geometry directly into a repeating hatch pattern. For a long and authoritative piece, we'll explore
Furthermore, a superior converter must prioritize . Native PAT files have a severe limitation: they are text-based and cannot handle an infinite number of line segments without bloating the file size and slowing down AutoCAD regeneration. Current converters often export every single line from the DWG as a separate line in the PAT file. This is inefficient and naive. A better converter would incorporate a "simplification engine" that identifies repetitive motifs. If a brick pattern contains ten identical bricks, the converter should define one brick and repeat it using the PAT language’s matrix codes, rather than listing every brick individually. This reduces file size by orders of magnitude and makes the resulting hatch responsive and lightweight.
