(First creates horizontal mortar every 50 units; second vertical mortar offset by 25 to create stagger.) Limitations: SuperHatch creates a visual hatch, but it
AutoCAD includes a little-known gem called SuperHatch (Express Tools). Limitations: SuperHatch creates a visual hatch
How to use SuperHatch for DXF to PAT:
Limitations: SuperHatch creates a visual hatch, but it doesn’t produce an editable .pat text file. It also consumes more memory than a native PAT.
| Tool | Method | Features | |------|--------|----------| | AutoCAD (Hatch command) | Manual | Export selected closed boundary as pattern (limited). | | HatchKit (TerraVerde) | Dedicated converter | Imports DXF, automatic tiling, supports arcs, preview. | | PatternMaker for Windows | Semi-automatic | Converts DXF lines to PAT, manual adjustment of periods. | | Python + ezdxf + custom script | Programmatic | Full control, open-source, requires programming. | | QCAD Pro | Built-in | Pattern export from selection, limited to simple tiles. | | FadeIn (for textile design) | Niche | Converts DXF weave structures to PAT. |
