We've run into this issue a couple times. This last time I sent the issue to my VAR and eventually it went to SW. The response was "It's the section view, delete it and recreate it". Well in this case that's an issue because doing so essentially means redoing the drawing. There is apparently no "Fix" or even way to avoid it. First has anyone else run into this and or has a fix for this. Second, this is the kind of thing that drives a person nuts. This apparently has been an issue for quite some time, years, and there's no fix and possibly no intention to fix it?
Here's what it's supposed to look like
Here's what it previews and prints like. This is just one view. The lines randomly occur in other views, BOM and pretty much everywhere. They are different from machine to machine.
