Here is the process for creating multi leaders in Solid Works
That's a link on your own internal network. No-one outside your organisation can see it.
For "multi-leaders" I just RMB on an existing leader & select "add new branch".
...or click on the end of the leader, hold down Ctrl, and drag.
That's a great tip, I use it quit often since reading about it here, but how do you remove one, I can't seem to find anything to delete/ hide/ suppress a leader?
For Multi-leaders, RMB on the leader you don't want & select "Delete Branch"
For single leaders, you nead to go into the properties for the note or dimension & select the leader tab, then click the leader with a red X next to it.
Click on the notation to highlight it, click on the small blue box at the end of whichever leader you want to delete, and hit Delete on your keyboard.
