Fitting a circle to points
WebJul 5, 2024 · to construct a circle out of the center points of other circles (or any elements which return a point like a sphere), select them all in the explorer and then RMB -> select all points of element. Red crosses will appear on the circle's centers. Then go to construct -> circle -> fitting circle in the menu. WebFor an optimization fit, you need a good starting point. You could: pick 3 reasonably separated points and fit a circle to them, or find the plane that best fits the N points, project all points onto the plane and then find the circle best fitting these using the algebraic or approximate Euclidean distance planar circle fit.
