i’ve tried the convex hull but that gives me straight lines between the circles.
what i need are arcs that i can adjust in the curvature. at the end it should look
similar to that - a nice clean curve with as few points as possible:
I tried both BiArc and BzSpan(Bezier Span, white curves). There may be a way around this but I added a ‘VecMag’ slider (yellow group) to “fudge” vector magnitude values for BzSpan. This must be adjusted based on distance between circles, whereas BiArc works well with three sets of curves (blue group, upper left).
three control points on the circle sections is just what i wanted.
but there is an offset in the middle of every arc. i wonder if this a break in the curvature or something?
it is still there even if i delete the control points (red) in the middle. no matter i will get that sorted.
1. somehow i don’t manage to access the circles to change size and position.
circle component says that there are 4 locally defined values. how can i get in there?
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.
