How to save imported hatch pattern permanantly?

Please increase the number of hatch pattern in the gallery

You can find all sorts of hatch patterns for free download on the web. Once you have them imported into one of your template files, save that file. The next time you open a file based on that template, all your new hatch patterns will be there.

In your other templates, you can import the template file with the hatch patterns and then save those as well.

Thanks a lot

Here is one place with lots of free hatch patterns: https://www.cadhatch.com/

Easy way to make haches in rhino?

If you are wanting to make your own hatch patterns from Rhino geometry, no, there is not. There was a plugin a long time ago - HatchMaker - but I don’t know if it still works or not.

There are guidelines on the web for making hatch pattern files yourself. They’re just text files and IIRC the hatches are composed exclusively of line segments defined by start and end points (no curves), plus various instructions on how to repeat the pattern.

Looks like Cad Hatch has a free pattern generator based on Excel: https://www.cadhatch.com/hatch-pattern-generator

And from scratch:

The Pattycake site (new to me) looks like a great place if you want to generate your own patterns via drawing… There is a free license and the paid pro license is pretty reasonable too…
