Most "online converters" are actually general file conversion platforms. For specialized CAD patterns, these are the most reliable options:
PAT files allow you to save custom geometry as a reusable hatch pattern across all your projects.
Platforms specializing exclusively in CAD file conversions usually yield the cleanest results because they understand complex AutoCAD line definitions.
You do not need expensive CAD software or local plugins installed on your machine.
: Automatically generates hatch patterns from your drawings by converting symbols or logos into PAT definitions. Summary Comparison Direct DWG Upload? Pattycake Editing existing code and previewing patterns. Toolblocks

If you already have a hatch pattern inside a DWG file and want to extract it as a standalone PAT file, use these specialized utilities: PatOut (by ARKANCE)
To help find the absolute best workflow for your specific project, tell me:
A DWG (AutoCAD Drawing) file is a proprietary file format developed by Autodesk, used to store design data, including 2D and 3D models, drawings, and other graphical information. DWG files are widely used in various industries, such as architecture, engineering, and construction, as well as in graphic design and manufacturing.
that allows you to select an existing hatch in a DWG and automatically generate a separate file from it. HGEN (Hatch Pattern Generator) : Available through
