Again, Affinity Designer isn’t making that clear. Is does this get created when I export? Is it because my paths might be drawn with different directions?
The double lines are what you get when you do Layer --> Expand Stroke, which a lot of us use for adjusting kerfs, but then you have to delete the extra line that results. Maybe you just missed that step?
Thanks for the answer @eflyguy, that’s right. I’m going to close this thread - if the problem reoccurs, go ahead and post a new topic. Thanks for letting us know about this!
