Hi there thank you for contributing to the Lucid for Developers Community space. As this issue does not appear to concern our APIs I’ve moved your post to our Lucid Suite Community space and someone will reach out to you shortly.
Hey there
Thanks for posting in the Lucid Community
Unfortunately at this time there is no way to curve the arrow shape. However as you said you can curve the arrow line that we have within Lucidchart and customize the thickness curve and line type.
I like the idea of having the ability to customize the arrows further to mimic the functionality you've mentioned -- I’ve gone ahead and converted this post to an idea within our Product Feedback space so that others can comment on and upvote it. Thank you for taking the time to let us know how Lucidchart can be better for you and your workflow -- I look forward to seeing your idea in the product! Cheers!![:beers: 🍻](https://cdn.jsdelivr.net/emojione/assets/png/1f37b.png?v=2.2.7)
