How to bind the end of annotation line to another object?

[nur91m]

Hi all.

What I need is:

1. Place 2 Symbols with leader

2. place 3rd symbol without leader

3. Bind the end of first symbol's leader to the start of second symbol's leader and the end of 2nd symbol's leader to 3rd symbol.

And when I move second symbol then end of 1st symbol's leader shoul follow it.

How can I do this with API?

Best Regards

Placing symbols is pretty easy. I would imagine you would need to use an IUpdater to move the leader of the first one. You would need to store the ID of the 1st symbol in the 2nd symbol to know which one to move. You could do that with ExtensibleStorage. But I wonder if its just easier to make a new family that looks like your image.
