Hi, you can see in the top view two closed planar curves. The two curves are positioned in a diagonal axis. I am trying to find the two external tangents that are connecting the two curves. The problem is that I just can find tangent components that are relating to circles.

I know that the two curves looking similar to a circle geometry, but because of special conditions, I can not make them perfect circular. They are more like an ellipse.

Thanks a lot for your help! Please find my GH file attatched.
