Drawing a custom link
Custom links are made up of segments. They are often used to show that communication occurs between two symbols.
1.Select the symbol where you want the link to begin.
2.Click a link handle, then drag to create the first segment of the link.
3.Press Control and Shift to end the first segment and begin a new segment.
You don't need to hold down the Control and Shift keys. Just press and release when you want to change direction.
5.To complete the link, click a connection point on the symbol where you want the link to end.
Tip: You can add new segments to a link you've already drawn. Select the link, then hold down Control and Shift and click the link where you want to make the segment. Drag the segment.
