I get a horizontal line in my circle design that I want to cut. How do I remove this?
It is almost certainly something wrong with your file. Post it, and talk about what you’ve done so far, in what programs or no one will be able to help much.
As a group we seem to love to help with stuff like this, but you have to provide some more context.
Yeah, it’s probably just an open path. If you can post the file (zip it, then drag and drop it into an open reply post) someone can take a look at it. No way to tell without looking though. 
I’m sorry you hit a snag.
I’m afraid we need a bit more information to narrow it down. Could you please upload the file you’re having trouble with so we can take a look? It may also help to post a screenshot of what you’re seeing in the app so we can better understand the issue.
Thanks in advance!
It’s been a little while since I’ve seen any replies on this thread so I’m going to close it. If you still need help with this please either start a new thread or email support@glowforge.com.
