Hello, I´m trying to find intersections of multiple curves on z-axis. I´ve multiple curves on x-axis and multiple curves on y-axis, and need to find their intersections on z-axis. Any ideas?
forgot to mention that the curves are not on same level on z-axis. Basically I´m trying to draw wires between supporting frames and beams that are hanging from the frames. 
An image or model you can share would be really helpful.
thx, but I solved it internally with help of colleague.
