Hi, I want to know if it is posible get the circle's center from two points and a determined radius with a mathematical solution... maybe with ones of the mathematical formulas? http://en.wikipedia.org/wiki/Circumference
I already made a geometrical solution (circle center with two points and radius in files): I put a circle in one point and a pipe in the other with the same radius and then I intersect them, I get two intersections but I just pick the first and thats the the circle's center that I want. Then I extract the subcurve of the arc between the two points. I made a pipe because the two points can be in different z coordinates, then I pretend to scale and orient the arc to the second point (I need the fixed radius in the horizontal plane, not in the diagonal). What I do is very messy, and I have a lot of point's set to do the same, so I would really apreciate if someone can help to do this in a more simple way.
