To come back on this, I don’t know if it is because of the shortest distance algorithm or
not, but it can get quite strange:
Same code as in your example (below), just dragged the yellow circle around a bit.
- in the last
example, why is the arrow offset between yellow and green? There is only one arrow so
there is no need for offsets.
There is no offset between yellow and green I think. This effect is the result of the
shortest distance algo I think > -=-=-=-=-=-=-=-=-=-=-=-=
