Is there any way to create our own custom hatching patterns? I’ve looked at the forum, but there doesn’t seem to be any instructions on this.
Yes. Rhino can import supported hatch patterns from another 3DM file or from and AutoCAD *.PAT file.
There are lots of Internet pages about AutoCAD hatch pattern files.
Hatch patterns are stored in Rhino 3DM files but can be imported from PAT files.
Thank you, John.
