Hi Jerry 

Thanks for posting in the community! Just to make sure that we are on the same page please review our Work with Lines article from the Lucidchart Help Center and let me know if you have any questions about their intended functionality.

A couple of specific things are worth noting from these resources:

• You can lock down your lines and shapes' position. To do so select the lines/shape you'd like to fix in a position and click the lock icon in the properties bar OR right-click on the shape and select "Lock" from the dropdown menu. To learn more about it please review the Lock/Unlock your Shapes section from the Lucidchart Help Center. 

• Enabling “Line Jumps” helps you manage overlapping lines by making it easier to follow a line’s path. Simply toggle on “Line Jumps” in your Page Settings (File > Page Settings) on the right of your canvas.

Hope this helps! Feel free to let me know if you have any further questions.
