I traced a few circles on a existing drawing with a path using the ofnuts plugin 'Shapes / On strokes / Circles' .Is there a plugin to define the center points of the circles?

Of each seperate circle or all of them combined?

This is not a mathematical answer. I am no mathematician
But
1. Each circle has it's own centre You should be able to find that by using guides
2 Not sure, but wouldn't the combined centre be the point where all the circles overlap?

Centerpoint from each circle, that's what I want without calculating.

The very function is also in ofn-path-to-shape and is called Shapes > On Strokes > Circle  > Crosshair: given a stroke with 3 points, it will draw a path with two strokes that intersect at the center of the circle.

   

Also, Shapes > On Strokes > Circle  > Circumcircle draws the circle that goes through the three points.

Oh Ok, it's inside a plugin, now I understand, thanks Ofnuts Smile
