Hi, I’m trying to create tangent arcs between rows of circles but I have some problems right now.
Since I have branches with even number of items and other with uneven number of items, my way of doing is not working properly.
I suppose there must be an easier way to deal with this but I can’t find the solution.
Is anybody can help me?
Also I’ve another question, when I have all the arcs, what is the best way to create a close outline with those circles and arcs as shown on the picture?
Thanks in advance! :slight_smile:

You can use offset:
