Hi @dan11one, thank you for posting in the Community and thank you @aparrish for chiming in!
It is not currently possible to create default connection points on shapes in Lucid.
We would love to hear more about how this specific feature would be useful to your work if you’re willing to share more via the following thread, which we also highly recommend to upvote:
However, it is possible to position your line connection point anywhere on your shape simply by clicking and dragging the line endpoint along the shape border wherever you’d like it!
An additional workaround involves importing a Visio diagram containing shapes with pre-added connection points, as Lucid's high-fidelity Visio integration often retains these points and allows lines to be glued to them.
