I’m trying to see if it’s possible to have crossing lines create an hop/jump so that the drawing remains clear instead of fuzzy with allot of crossing lines.
The image shows what I mean by a line hop:
Sadly, up to this point I haven’t been able to achieve this with LibreOffice nor have I been able to find anything in wiki’s or on this site.
So my question is, can LibreOffice Draw create line hops/jumps?
Well, AFAIK, it’s impossible, but you can fake it.
Select Basic Shapes>Circle Pie.
Create a half circle, change the fill to none.
Modify>Break then Modify>Break again and then delete the 2 line segments.
Add this item to your gallery for easy access.
Drop it over the line you want to cross and then use line segments on either side.
@hyogapag, I was afraid that I’d have to trick my way into a solution 
Your source also shows a link to the actual feature request for OpenOffice.org ( https://issues.apache.org/ooo/show_bug.cgi?id=81290 ). I’ll see if I can find a place to submit a feature request for LibreOffice 
The above answer should still remain as the only correct one.
I’ve submitted a feature request for LibreOffice, after searching I wasn’t able to find a request for this particular feature.
You can find the feature request for LibreOffice on this page:
