Hi,
I am trying to get the x and y coordinate an outline produces by two or three intersecting circles as shown in the figure. Coordinate of the two circles are available below.
How can we do this automatically? I have hundreds of figures like this with known coordinate. The shape can be arbitrary, not necessarily circle.
What I want is just to get the x and y coordinate of the final shape.
