Hatch patterns are stored in Rhino 3DM files but can be imported from PAT files.

Thanks!

Only thing different in this version is that while it still writes a *.pat file, the hatch pattern will also be added to the file. As for documentation for use, the plug-in adds one command: makeHatch. The quick rundown for the options would be: X and Y padding is how much room to add between repeating the curves selected. Currently you ca…
