As shown in the picture, I want to reverse-engineer the Circle TanTan component to figure out the target I desire - specifically, to determine the diameter of the circle. I hope more experienced individuals can provide me with some hints or solutions.

Is this what you mean?

Alternative:
Offset both curves with the diameter/2 (=radius) and check for intersections.
If more than one choose first or second intersection with a toggle and use intersectionpoint as origin for your new circle.
