Hi,

I have a bunch of CGAL 2D points and 2D circles that are parameterized
by a 2D linear geometry kernel (in this case
CGAL::Exact_predicates_exact_constructions_kernel).

I'd like to create 2D circular arcs using these linear points and
circles as construction parameters. I can see the relevant circular
arcs are not in the linear 2D geometry kernel but the 2D circular
geometry kernel. (Although there is a Circle_2 in the linear kernel
but no arcs).

So I need to create instances of Circular_arc_2 parameterized by (say)
CGAL::Exact_circular_kernel_2. For that I need instances of
Circle_2<Exact_circular_kernel_2> and
Circular_arc_point_2<Exact_circular_kernel_2>. Is there a
straightforward way or indeed, any way, to convert the linear kernel
circles and points I have between these two kernels?

Thanks in advance,

Stu
