Oh I see. It's starting to make sense. Thank you all very much for your help. I think you have answered all my questions for now. If someone wants to add something to this discussion, feel free to do so.

Try harder? That is the most natural way in CGAL. If you have trouble with
it, maybe you can ask here with specific code. Maybe there is a real
obstruction that prevents from using this solution here, but you would
likely be asked to explain it before integrating code that uses a different
strategy.

Actually, my problem is that the constructor of Sphere_d is not the same as
constructing a Circle_2. Sphere_d takes an iterator of Point_d whereas
Point_2 only takes three points or a center with a radius. Do you know how
I could work around that?

Your traits class would not only provide the type Sphere_d, it would also provide a functor Construct_sphere_d. In the adaptor for Kernel_d, that is already provided. In the adaptor for Kernel_2, you would need to implement the functor so it reads the first 3 values of the iterator and calls Construct_circle_2 on those.
