I am not sure what its called, but its basically a way to show that a line in a flowchart does not cross over another line. So instead it does a little Hop of sorts over the line to show its separated.
How do I do this in Whimsical flowcharts?
In my software I call them pipehops, they’re used to indicate that the pipes don’t connect.
I can see that they’d be a good idea in Whimsical. They’re trickier to implement than you’d think though (what direction, which line hops, etc)
In the mean time, think about changing the color/width of one of your lines, and that will help communicate that they cross, not intersect.
