Hi Rebecca

Thanks for reaching out to Lucidchart support. Unfortunately it is not possible to change all lines in a chart into smart lines in a non-manual way or to define which part of the shape a smart line should attach to. 

However we're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our feature request form? Ideas submitted to this form are passed on to the product development team for their consideration.

Hey ​@Abby S checking in on this, someone referred me to this post for a similar question I just posted. Any progress on bulk replacing regular lines with smart lines in the last six years? Or is that probably just not something that will get developed?

Just tagging others who can answer: ​@Kelsey Gaag ​@Amelia W ​@Mj Z ​@Ambar D 

Thanks ​@aparrish for tagging me here and ​@Sam Gechter for adding your question to this thread! 

I’ve responded similarly in your post below, but adding this here too. If select ‘View’, then ensure that ‘Enable line connections’ is selected, all your lines and shapes should behave as smart lines. Does that result in the experience you’re hoping for?

Please let me know if you’re still running into problems or have other questions! Happy to help!
