Bounding curve around set of circles

Create your own list of circles any way you like. I modified this model for another thread with a ‘Random Subset’ feature (pink group) to use a subset of the list of circles as a quick way of trying any two circles. Then I found I needed to sort the circle segments differently (teal group).

The “tube” (Pipe) is just cosmetic to show the complete perimeter curve, which is constructed from curve fragments. (38.4 KB)
