HatchKit : Widely considered the industry standard for creating and managing AutoCAD and Revit hatch patterns. It allows you to import DXF files and visually edit them.
Converting DWG motifs to PAT files is practical when motifs are composed of repeatable linear elements; success depends on accurate repeat-unit detection, angle clustering, and careful control of offsets/dash sequences. For one-off needs, CAD manual workflows suffice; for scale or automation, implement scripted pipelines using DXF/DWG reading libraries and the heuristics outlined above. dwg to pat converter better
