As in the video below.https://youtu.be/S4rhj6IHWHA
I have created two objects that are kind of rectangular.
When I try to join the two objects, there is always a faint white line between them. Even though theoretically they are joined.
Before you ask, I have already selected both objects and enabled "Object Hiting", but this annoying white line between the objects is still there.
Any solutions please?
One workaround is to create duplicates of the objects in the same locations as the original objects.
For more information about that, see comments from Hendrik Wagenaar in this thread: Annoying white lines in traced images.
