Hi @AmirYanai, thank you for posting in the community! It sounds like you may be looking for the option to add line jumps to your lines (see screenshot below). Is this correct? 

You can easily enable this option in your document settings. To do this, open the Document Settings window via File> Document Settings. 

From there, click ‘Lines’ and toggle ‘Show line jumps’ on. This will show the jump when your lines overlap in your diagram. 

For more details about styling lines in your diagram, I recommend checking out this Add and style lines in Lucidchart article from the Lucid Help Center.

Please don’t hesitate to let me know if this is not what you are looking for, or if you have any questions. Hope this helps! 

Thanks!

That was very helpful.

Amir.
