    How i can calculate this in coffee?
    Cut of a sphere with a line is not a problem. But a sphere with C4D spline object - i dont know.

    You can get a point along the spline as well as the tangent. Then you can just search for the cutpoint numerically. (See SplineObject.)

    is there Xpress/COFFEE combination for this? Mikael your method doesn't give exact point but only an estimation.

    I doubt there is an analytical solution to your problem, you'll have to go with some kind of numerical estimation anyway. The best is probably to use the Line Segments generated from the Spline anyway, because otherwise you won't be able to include any effects that come from deformation. Intersection of Line Segments with Spheres should be pretty simple again.

    Hope that helps
