Is there anyway to trim a hole in an existing hatch pattern without having to recreate it?
Thanks
No, but you can turn on controlpoints and edit a hatch.
I wish for a full edit too, kind of like how we edit a block would be nice.
Fastest way to edit now is to duplicate the boundry of the hatch, edit and/or add curves to that, then rehatch, and match to the old hatch, and delete the old.
Thanks. The dupBorder trick works nice.
Yes more hatch edit features would be nice.

Also on my wishlist!
Hey djnelson75
I have been working a lot with hatches lately, and missed this function a lot, so I decided to give it a try and wrote this script that automates basicly what Holo wrote.
Let me know what you think: is it helpful? noticed any bugs? is it user friendly? is it something you would do differently? Thx for your input!

hey
any idea how to insert this script into rhino?
Hello - note Trim works on hatches in V7.
The post above has the complete macro for running the script, though, so far it is not working here.
